JavaScript is an incredibly flexible programming language. Once you’ve learned it, the possibilities are endless: you can code on both the client-side (frontend) and server-side (backend) using Angular and Node.js. Additionally, you may construct online, mobile, and desktop applications utilising React.js, React Native, and Electron, as well as participate in machine learning.

You can take a JS course to learn all of these in detail and start your journey as a JavaScript developer.

JavaScript is required if you wish to work as a frontend developer. However, as a JS specialist, this is not the only job route available to you. After mastering this critical programming language, you may pursue careers in:

  • Full-stack development
  • Game development
  • Software engineering
  • Machine learning
  • Artificial intelligence

Here we will learn about why JavaScript is so popular and the best JavaScript tutorials available online.

JavaScript – What is it?

JavaScript is a scripting language that is:

  • Fast
  • Cross-platform
  • Interpreted

⦁It is well-known for web page creation, but it is widely used in a variety of non-browser settings. JavaScript programming may be used for:

  • Client-side
  • Server-side

JavaScript has a standard object library, such as Array, Date, and Math, as well as a basic set of language components such as:

  • Operators
  • Control structures
  • Statements

Key Features


It provides objects that allow a browser to be controlled and its Document Object Model (DOM). As an example, consider the case where client-side extensions enable an application to add items on an HTML form and respond to user actions such as mouse clicks, form input, and page navigation. AngularJS, ReactJS, VueJS, and a slew of others are useful client-side libraries.


It provides items necessary for executing JavaScript on a server. For example, if server-side extensions enable an application to interface with a database, maintain data continuity from one programme invocation to the next or conduct file operations on a server. The most popular framework these days is node.js.

Important Points About JS

There are two ways to include JavaScript in your HTML file: 

  • Internal JS: We may include JavaScript directly in our HTML file by enclosing it in the <script> element. The <script> tag can be inserted inside the <head> or <body> tags, depending on the situation.
  • External JS: We may write JavaScript code in a separate file with the extension.js and then link to it within the <head> element of the HTML document containing the code.

Nowadays, JavaScript is a general-purpose programming language, which means that it operates on every component of the software stack. Although it is most frequently used on the client-side (or frontend), many people now use JavaScript on the server-side (aka backend).

When JavaScript code is used on the client-side, it is read, interpreted, and executed within the user’s web browser. When used as a server, it is installed on a distant computer.

This javascript training course is part of Johns Hopkins University’s Ruby on Rails Web Development Specialization. However, it is created and structured in such a way that it may be taken independently; no prior understanding of Ruby on Rails is required to finish it.

This course covers all of the necessary and fundamental website coding abilities, not only the “how” but also the “why,” to ensure that learners fully get the rationale behind their actions.

The course focuses on the foundations of the Javascript programming language. It covers nearly everything, from fundamental programming structures and Javascript types to objects, functions, arrays, closures, and scope separation.

There is an entire module devoted to developing web applications using JavaScript, in which students learn about HTTP, the DOM API, how to configure and manage Ajax requests and answers, and how to process JSON data.

University of Michigan

This JS Certification is included in the University of Michigan’s Web Design for Everyone: Fundamentals of Web Development & Coding Specialty; however, it may be taken independently of the whole specialisation. This course teaches learners how to implement interactivity into a website using JavaScript.

Students are exposed to the JavaScript language’s fundamentals in this course, which includes extensive coverage of variables, loops, and functions. Debugging tools are also taught.

After this course, you will be able to comprehend how JavaScript uses the Document Object Model (DOM) to identify and edit particular portions of a page, react to DOM Events, and dynamically adjust the page’s content and layout.

The course has a final project – the development of an interactive HTML5 form capable of accepting and verifying input.

University of Pennsylvania

This JS course is part of the University of Pennsylvania’s Professional Certificate Program in Computer Science Essentials for Software Development. This course teaches you how to use JavaScript to create dynamic, interactive, and data-driven online applications.

It serves as a primer on current web development with JavaScript. Not only will you master the fundamentals of HTML and CSS web page construction, but also the sophisticated web page layout and responsive design tools.

This Course is divided into four parts that begin with the fundamentals of JavaScript, including the language syntax. The course then moves on to more sophisticated topics like callbacks, events, and asynchronous programming, as well as jQuery, DOM manipulation, and event handling.

Additionally, you will learn how to use JavaScript libraries and frameworks on both the client and server-side.


A JavaScript developer with entry-level experience can expect to earn roughly Rs. 350,000 per year. In India, you can expect to earn roughly Rs. 1,000,000 per year after gaining 5-6 years of expertise. Keep in mind that your pay will be determined by your ability level.

In order to become a senior-level JavaScript developer, you will need to earn more experience. The more experience you gain, the better the income you may expect.


Numerous programming languages exist to handle the same sort of challenges in any area or software development environment. However, we have stated that JavaScript has a “monopoly” on the frontend market for online applications.

This fact alone positions it in a superior position to other languages. The most intriguing aspect of finding jobs in JavaScript is that all frontend tools/frameworks are now JavaScript-based, and it is strongly suggested to understand JavaScript in full. That is, if we want to work with React, Vue, or even Angular (which utilises TypeScript as a programming language), we will need to be familiar with JavaScript.

Thus, knowing and comprehending JavaScript will enable you to obtain decent and well-compensated work. There is a dearth of specialists with a basic understanding of the JavaScript programming language in today’s market. Thus, if you are planning to learn JavaScript, you may be set for a bright future ahead.
