What is JavaScript?

JavaScript is a text-based programming language that allows you to construct interactive web pages on both the client and server sides. Whereas HTML and CSS provide structure and aesthetics to web pages, JavaScript adds interactive components that keep users engaged. The search box on Amazon, a news recap video posted in The New York Times, and refreshing your Twitter feed are all examples of JavaScript that you may encounter daily.

Changing a static web page into an interactive one, including JavaScript improves the user experience. To summarize, JavaScript provides functionality to web pages.

What is JavaScript used for?

JavaScript is mostly utilized in web browsers and web-based applications. However, JavaScript is utilized in software, servers, and embedded hardware controls in addition to the Web. Here are a few examples of how JavaScript is used:

1. Including interactive features in websites

Users can interact with web pages using JavaScript. On a web page, there are essentially no restrictions to what you can accomplish using JavaScript – here are a few examples:

• With a press of a button, you may reveal or hide more information.
• When the mouse lingers over a button, it changes color.
• On the site, you may scroll through a carousel of photographs.
• Zooming in or out on a photograph
• Using a website to display a timer or countdown
• Audio and video can be played on a web page.
• Animations are displayed.
• Using a hamburger menu with a drop-down menu

2. Developing online and mobile applications

For designing and constructing online and mobile apps, developers can employ a variety of JavaScript frameworks. JavaScript frameworks are collections of JavaScript code libraries that give developers pre-written code to use for common programming features and tasks—basically, a framework around which to construct websites or online apps.

React, React Native, Angular, and Vue are all popular JavaScript front-end frameworks. Many businesses utilize Node.js, a JavaScript runtime environment based on the JavaScript V8 engine in Google Chrome. Paypal, LinkedIn, Netflix, and Uber are just a few well-known examples.

3. Developing server apps and building web servers

Aside from websites and apps, developers may use JavaScript to create basic web servers and Node.js to develop back-end infrastructure.

4. Game Development

Of course, you can make browser games with JavaScript as well. These are excellent methods for new developers to put their JavaScript abilities to the test.

Why should you choose JavaScript instead of another programming language?

Apart from the endless possibilities, there are other reasons why web developers should choose JavaScript over other programming languages:

• The only programming language that is native to the web browser is JavaScript.
• The most widely used programming language is JavaScript.
• To begin started, you only need a small amount of money.
• It’s an enjoyable language to learn.
