How to Become a JavaScript Developer?

A web developer is a programmer who specializes in the development of applications and services for the World Wide Web. They are responsible for designing, coding, and building websites and web applications using a variety of programming languages and frameworks.

Web developers may also be involved in the maintenance and updates of existing websites and web applications. They typically work alongside web designers to create visually appealing and user-friendly websites. Web development can be divided into front-end development, which focuses on the user-facing side of websites, and back-end development, which focuses on the server-side functionality of websites.

Here is a simple example of JavaScript that writes “Hello World!” to the browser’s console −

console.log("Hello World!");

You can run this code by creating an HTML file with a script tag, and running the file in a web browser. The script tag should look like this −

   console.log("Hello World!");

The above code will output the “Hello World!” in the browser’s console which can be open using the developer tool.

Note − The above process is a general guideline, you may also want to learn more about front-end development, back-end development, and other areas of web development as well.
