Yes, Programming Language is the most important prerequisite for almost every discipline whether it be Web Development, Machine Learning, Data Science, or any other. And, every year, we see how the ranking of these Programming Languages fluctuates in accordance with their demand & popularity among the developers. Meanwhile, you’re required to be updated with all these latest trends and indices of Programming Language to stay relevant in the tech market. In particular, beginners are strongly required to consider several crucial aspects such as demand & popularity, job opportunities, applications, etc. before opting out for a particular programming language.

1. JavaScript

Many Languages came and disappear but JavaScript is one of the those few renowned languages that is enjoying a high run and demand in the programming world.

JavaScript was created in 1995 and was initially known as LiveScript. However, Java was a very popular language at that time, so it was advertised as a “younger brother” of Java. As it evolved over time, JavaScript became a fully independent language. Nowadays, JavaScript is often confused with Java, and although there are some similarities between them, the two languages are distinct.

2.Python

Python has been one of the most popular programming languages for a while now. It’s easy to learn and versatile, which is why it’s favored by many software developers, especially those in machine learning and data science. In 2022, the open source programming language will still be in high demand due to its simplicity and readability.

Python has been the favorite language of almost every individual who is just starting with the programming domain for the last many years. the primary reason behind this is a quite simple syntax that make it easy to read , learn and use.

The next few years are going to see a huge increase in the popularity of Python as it continues its reign as this generation’s most popular programming language. The elegant yet straightforward syntax makes learning easier than ever before, not just for beginners but also experts who want something they can understand quickly without having too many functions or keywords memorized.

Python is the best programming language for beginners and experts alike. It’s simple yet powerful, which makes it perfect to use in any number of fields from machine learning (ML), deep-learning databases, science data analysis or statistics computing with ease.

3. Java

Java is more of a serious server-side language and has got very high demand from the enterprise application community and the services that require high scalability and consistency. The more agile application teams ( like startups ) are relying on don’t the options like Python and Node.js for quick application.

For server-side Java, you are required to also know different frameworks like Spring for an effective career. Almost any organization will be having some critical services running in Java even though the primary services are in other languages.

4. Go

Companies such as Uber and Google use the Go programming language. Google’s Go programming language is statically typed and has a syntax similar to C. Multithreaded, the language can be used in distributed systems, cloud computing, as well as other applications.

The best thing about the language, however, is its ability to overcome many fundamental problems such as slow compilation and execution, a lack of a large standard library, and so forth.

5. Swift

A few years ago, Swift made the top 10 in the monthly TIOBE Index ranking of popular programming languages. Apple developed Swift in 2014 for Linux and Mac applications.

An open-source programming language that is easy to learn, Swift supports almost everything from the programming language Objective-C. Swift requires fewer coding skills compared with other programming languages, and it can be used with IBM Swift Sandbox and IBM Bluemix.

6. PHP

The PHP Hypertext Preprocessor (PHP) is a programming language that allows web developers to create dynamic content that interacts with databases. PHP is basically used for developing web based software applications. This tutorial helps you to build your base with PHP.

Why to Learn PHP?

PHP started out as a small open source project that evolved as more and more people found out how useful it was. Rasmus Lerdorf unleashed the first version of PHP way back in 1994.

PHP is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Web Development Domain. I will list down some of the key advantages of learning PHP:

PHP is a recursive acronym for "PHP: Hypertext Preprocessor".
PHP is a server side scripting language that is embedded in HTML. It is used to manage dynamic content, databases, session tracking, even build entire e-commerce sites.
It is integrated with a number of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.
PHP is pleasingly zippy in its execution, especially when compiled as an Apache module on the Unix side. The MySQL server, once started, executes even very complex queries with huge result sets in record-setting time.
PHP supports a large number of major protocols such as POP3, IMAP, and LDAP. PHP4 added support for Java and distributed object architectures (COM and CORBA), making n-tier development a possibility for the first time.

JavaScript

JavaScript is a popular web scripting language and is used for client-side and server-side development. The JavaScript code can be inserted into HTML pages that can be understood and executed by web browsers while also supporting object-oriented programming abilities.

Question: What is JavaScript?

Answer: JavaScript is the most popular web scripting language, used for both client-side and server-side development. Supporting object-oriented programming abilities, the JavaScript code can be inserted into HTML pages that can be understood and executed by web browsers.

Question: How is JavaScript different from Java?

Answer: Java is a programming language, whereas JavaScript is essentially a scripting language. Developers use Java for building applications that can run in a virtual machine, an operating system, or inside a browser. Contrastingly, JS code is meant to run inside a browser only.

Question: Please explain the various JavaScript data types?

Answer: There are a total of 7 basic data types supported by JavaScript. Each one of them is briefed up as follows:

Boolean – Represents true and false values.
Null – Represents empty, nothing, and unknown type of values
Number – Represents both integer and floating-point values.
Object – Used for storing collections of data or more complex entities
String – Represents single-character, multi-character, and alphanumeric values.
Symbol – Used for creating unique identifiers for objects
Undefined – Represents value not assigned. If a variable is only declared and not assigned in JS, it represents the undefined data type.

Question: Can you differentiate between let and Var?

Answer: Both let and var are used for variable and method declaration in JavaScript. However, the most important difference between the two JS keywords is that while the var keyword is function scoped, the let keyword is block scoped.

Question: Difference between = = and = = = ?

Answer: = is used for Assigning values to a variable in JavaScript

= = is used for comparison between two variables irrespective of the data type of variable

= = = is used for comparison between two variable but this will check script type , means it will check data type and compare two values.

Question: Could you name some built-in methods in JavaScript?

Answer: Following are some of the inbuilt methods in JavaScript:

anchor() – Creates an HTML anchor to be used as a hypertext target
ceil() – returns the smallest integer that is greater than or equal to the given number
concat() – Combines two strings and returns the newer string
constructor() – Returns the function that created the corresponding instance of the object
Date() – Returns the present date and time
Date.parse() – Parses a string representation of a date and time and then returns the internal millisecond representation for the same
exec() – Searches for a match in the string parameter
filter() – Creates a new array with all the elements of the array for which the filtering function returns true
font color () – Displays a string in the specified color
link() – Creates an HTML hypertext link that requests another URL
localeCompare() – Returns a number that indicates whether a reference string comes before, after, or is the same as the given string in the sort order
match() – Used for matching a regular expression against a string
pop() – Removes and returns the last element from an array
reduce() – Applies a function simultaneously for two values of the array to reduce them to a single value
round() – Rounds off the value of the given number to the nearest integer and returns the same
slice() – Extracts a certain section of a string and returns the remaining string
some() – returns true if at least one element of the array satisfies the provided testing function
toLocaleString() – Return a string value of the current number in a format that depends on the browser’s locale settings
sup() – Displays a string as a superscript
toSource() – Returns a string containing the source of the Boolean object
toUpperCase() – Converts a text to uppercase
valueOf() – Returns the primitive value of the specified object

Question: Please explain Self Invoking Function and its syntax.

Answer: Functions that are automatically invoked are termed as Self Invoking Functions. These are also known as Immediately Invoked Function Expressions and Self Executing Anonymous Functions. The general syntax of a Self Invoking Function is:

(some_function () {
    return () }) ();         @Hi Fi Tech Talk 

Typically, a function is defined and then invoked. However, if there is a need to automatically execute a function at the place where it is given and not be called again, then anonymous functions can be used. Such functions have no name, and thus the name.

Question: What do you understand by Closures in JavaScript?

Answer: Closures provide a better, concise, creative, and expressive writing code for JavaScript developers and programmers. Technically speaking, closures are a combination of lexical environment and function.

In other words, a closure is a locally declared variable that is related to a function and stays in the memory when the related function has returned. The closure contains all local variables that were in-scope at the time of the closure creation.

The following code snippet demonstrates using a normal function in JavaScript:

function greet(message) {
console.log(message);
}
function greeter(name, age) {
return name + " says Hey!! He is " + age + " years old";
}
var message = greeter("vishal prince raaz", 24);
greet(message);

The aforementioned function can be represented in a better way by using closures. This is demonstrated in the following code snippet:

function greeter(name, age) {
var message = name + " says Hey!! He is " + age + " years old";
return function greet() {
console.log(message);
};
}

// Generate the closure

var vishalGreeter = greeter("Vishal prince raaz", 26);

// Use the closure

vishalGreeter();

Question: What are the differences between substr() and substring()?
Answer : The differences between substr and substring methods are given below:
substr()
substring()
It is used to return the characters in a string beginning at the specified index and returns the number of characters based on length provided
It is used to return the characters in a string beginning at the specified index and returns the number of characters based on length provided-1
var x = "hello";
console.log((x.substr(1, 4) == "ello"))
It will print true in the log
var x = "hello";
console.log((x.substring(1, 4) == "ello"))
It will print false in the log
var x = "hello";
console.log((x.substring(1, 5) == "ello"))//print true in console

Question: What are the differences between array and object?
Ans: The differences between array and Object are given below:
Array
object
The array uses the numbered indexes to access the element in it
The object uses the named indexes to access the members in it
You should use an array when you want the element name to be number
You should use an object when you want the element name to be a string
It is an ordered collection
It is a collection of unorder properties

Question: What is DOM?

Ans. Dom is a W3C (World wide web consortium) standard, when the HTML page loads in the browser, the browser creates the DOM (Document object model). It defines the HTML element as an object and allows scripts to dynamically manipulate the content, and the structure of the document.

@Hi Fi Tech Talk

Question : What is BOM?
Answer : which provides interaction with the browser, the default object of the browser is a window. Various property provided by windows is a document, history, screen, location, navigator.

Question : What is the usefulness of the window object?
Answer :A browser’s history object could be used to switch to history pages like back and forward from the existing page or another page. 3 methods of history object are as follows:

history.back() – This method loads the previous page.
history.forward() – This method loads the next page.
history.go(number) - Its number may be positive (for forward) or negative (for backward). It will load the provided page number.

Top Best Code Editor for Developer

Code Editor are simply pieces of text editing software designed around the intent of editing code. While you can write code in any text editor, such as Notepad or Microsoft Word, code editors tend to come with specific key features that are better geared for dealing with code. This can include things like syntax highlighting (which colors certain keywords and makes code easier to read), the ability to select and edit multiple lines for indentation, and more. While the features are different from code editor to code editor, they were all designed with the specific purpose of making editing code easier for programmers.

1. Visual Studio Code

Visual Studio Code is a code editor developed by Microsoft, and surprisingly, it's open-source software. Of all the code editors in our list, this is probably the closest to being an IDE. It's very robust – and it's one of the slower programs when starting up. However, while using it, VS Code is quick and can handle quite a few interesting tasks, such as quick Git commits or opening and sorting through multiple folders’ worth of content.

VS Code has seen a meteoric rise in popularity. It's continually growing its user base and drawing developers away from other editors. It has a built-in terminal, as well as built-in Git support, both of which are big winners among fans. The ‘IntelliSense’ feature offers autocompletion of code and data on the parameters of functions and known variable names.

2. Sublime Text Editor

Sublime was initially release in 19 January 2008.Sublime Text really changed the way the best code editors work. It's lightweight, open and ready to edit your file almost as soon as you've managed to click the button. This responsiveness is one of the things that makes it the best code editor in its class overall. If you want to open a file and make a quick edit, waiting a few seconds for loading may not sound like much, but the delay can quickly grow tedious.

Another big benefit of Sublime Text is that it's wildly extensible, with a huge and ever-growing list of plugins available to install via the package manager. Options include themes to customize the editor’s appearance, code linters (which can assist with more quickly locating any errors in your code), Git plugins, color pickers, and more.Sublime Text is free to download.

3. Bracket

Brackets was initially release in 13 may 2018 .Brackets is a lightweight, yet powerful, modern text editor. We blend visual tools into the editor so you get the right amount of help when you want it without getting in the way of your creative process. You'll enjoy writing code in Brackets.
