Are you planning to learn web development or boost your programming skills with a JavaScript course in 2023? With the constantly changing landscape of web development, the value of a JavaScript course remains a topic of discussion. Don’t worry; this article dives into the current significance of JavaScript in web development so that you can make an informed decision.
What Is JavaScript, and What Does It Do?
JavaScript is an all-purpose programming language that makes websites dynamic, interactive and user-friendly. Then what about HTML? Isn’t it used to build websites? Hyper Text Markup Language or HTML is used to define the basic content and structure of the website, like titles, headings, paragraphs, texts, etc. Additionally, CSS (Cascading Style Sheet) is used to specify how the content and other web page elements are displayed, like their colours and fonts.
Confused? Let’s take an analogy by comparing a website to a doll. HTML defines the body, while CSS defines its clothes. Now you need the doll to sing, dance and do other things, which you can program using JavaScript. Thus, JavaScript adds functionality to a website.
JavaScript is used in both front-end and back-end web development. Apart from creating websites, you can use it to create browser-based games, cloud games, mobile apps, web apps and a lot more, thanks to its various libraries and frameworks. This is why JavaScript is the most commonly used programming language.
How to Learn JavaScript?
There are different ways to learn JavaScript as a beginner, but the best approach requires you to learn the basics of HTML and then CSS first. Both are very easy to learn and help build a base for JavaScript; there are also plenty of resources online. Next, you need to learn plain JavaScript – only the basics initially and not any libraries.
Once your JavaScript (JS) fundamentals are strong, you can start learning different frameworks depending on your needs: front-end, back-end, web apps, full-stack development, etc. There are tons of JavaScript libraries and frameworks that you will use later on in your career, but not all have the same functionality.
Is a JavaScript Course Still Worth It in 2023?
The short answer is yes. Listed below are the reasons why you need to take up a JavaScript course to excel as a developer.
1. Beginner-Friendly
Compared to other programming languages, JavaScript is one of the easiest languages to learn. You don’t need to install any new software, as every browser has JS pre-installed. In Chrome, you can go to the menu-> More tools-> Developer Tools, and select the Console tab to practise. Alternatively, you can press Control+Shift+J in Windows (Command+Option+J in Mac). You can start coding right away and see the results immediately!
JavaScript supports object-oriented, functional and imperative styles of programming, which can help you learn other programming languages (like python, java, C++ etc.) later on. Also, there is a massive online developer community for JavaScript that you can rely on for all the help you need.
2. Prominently Used in Web Development
JavaScript is one of the core languages used to build websites – both front-end and back-end. In fact, 98% of websites use JavaScript for the back end (client side) along with third-party libraries. Not only websites, but web applications are also built using JS.
Some of the most prominent JS front-end libraries are jQuery, React.js, Angular.js, Ember.js, Polymer.js, etc. Frameworks like Nest.js, Node.js, Express.js, GraphQL, Meteor.js, etc., are used for the back end.
3. Applications Beyond Web Development
JavaScript is a versatile programming language and is used in various fields apart from web development. It is used in mobile and game development, as JS frameworks are often used for the front end. You can also use it to build Android and iOS native apps, as both Google and Apple provide JS support in their application development toolkits.
Another area is Big Data. JSON (JavaScript Object Notation) document is a major standard for data exchange on the web. NoSQL databases often use JSON to store records as it is the best fit to connect the application with big data. Other areas include cloud computing, machine learning, artificial intelligence and blockchain.
4. An In-Demand Skill That Pays Well
The knowledge of JavaScript opens doors to many career opportunities apart from being a web developer. Even beginners can find plenty of opportunities if they have a sound knowledge of JS.
Today, almost every business has an online presence, and they may need more than a website. Various software tools and applications support their business operations. And often, these are web-based and cloud-based services/software built using JS Frameworks!
According to AmbitionBox, the salary of a JavaScript Developer in India can range from INR 1.8 Lakhs to INR 12 Lakhs with an average of INR 4.2 Lakhs per year.
