Basic Syntax of JavaScript

Image description
JavaScript can be implemented using JavaScript statements that are placed within the <script>... </script> HTML tags in a web page.

You can place the <script> tags, containing your JavaScript, anywhere within your web page, but it is normally recommended that you should keep it within the <head> tags.

The <script> tag alerts the browser program to start interpreting all the text between these tags as a script. A simple syntax of your JavaScript will appear as follows.

<script> 
JavaScipt Code like below.
document.write("Basic Print method in JavaScript"); 
</script> 
Enter fullscreen mode Exit fullscreen mode

Basic JavaScript Code:

Let us take a sample example to print out "Hello World". We added an optional HTML comment that surrounds our JavaScript code. This is to save our code from a browser that does not support JavaScript. The comment ends with a "//-->". Here "//" signifies a comment in JavaScript, so we add that to prevent a browser from reading the end of the HTML comment as a piece of JavaScript code. Next, we call a function document.write which writes a string into our HTML document.

This function can be used to write text, HTML, or both. Take a look at the following code.

<html>
   <body>   
      <script language = "javascript" type = "text/javascript">
         <!--
            document.write("The Dev Team!")
         //-->
      </script>      
   </body>
</html>
Enter fullscreen mode Exit fullscreen mode

Output:
The Dev Team!
