Intro to Javascript

Javascript is an object-oriented, lightweight, single-threaded scripting language. It is widely used to make interactive and dynamic web pages. It is also used for client-side validation.

To print "Hello World" in javascript:

<html>
  <body>
    <script>
         console.log("Hello World");
    </script>
   </body>
</html>

The above code will print Hello World on the console.

Let's discuss the key terms used in the above definition:

  • Object-oriented means JavaScript can work with objects and classes.

  • Lightweight means it uses significantly less memory and has straightforward syntax and semantics.

  • Single-threaded means JavaScript can process only one command at a time.

  • Scripting Language is a programming language subcategory that provides instructions to another language to operate in a certain way.

  • Dynamic web pages show information according to the users of that website.

We will look at different ways to create a variable in the next blog.
