How to write a "Hello World" program in JavaScript

The first step to getting familiar with a new language is to write a simple “Hello World” program.

A web browser is a suitable option for our JavaScript working environment where we will write and test code.

The first step to writing our program is to attach a JavaScript script to a web page. For server-side environments (like Node.js), you can execute the script with a command like “node myProgram.js”

JavaScript programs can be inserted into any part of an HTML document with the help of the <script> tag.

Now, the only thing left is to display the “Hello World” message inside of the <script> tags so that this alert can be used.
