Javascript is weakly typed

Javascript is weakly typed language. You can assign any type of data to a variable.

For example,
var a = 10;
a = "Hello World";
a = true;
a = 10.09;

As you see above example, I can able to assign a number, string, boolean values to same variable ‘a’. But it is not the case in strongly typed languages like C and Java.

variables.html
<!DOCTYPE html>

<html>
 <head>
  <title>Variables</title>
 </head>
 
 <body>
  <script type="text/javascript">
   var a = 10;
   document.write("Value of a is " + a + "<br />");
   
   a = "Hello World";
   document.write("Value of a is " + a + "<br />");
   
   a = true;
   document.write("Value of a is " + a + "<br />");
   
   a = 10.09;
   document.write("Value of a is " + a + "<br />");
  </script>
 </body>
</html>
