VARIABLES SYNTAX

  1. var

    • var variableName = "Varable-Value;" // Right Syntax

      Eg:

       var name = "Brainchild";

 var age= 20;

 var placeName = "Brainchild";

    • var variableName = "Varable-Value" // Wrong Syntax

      Eg:

        var name = "Brainchild" // Semicolon ( ; ) is missing.

 var placeName = Brainchild; // Quotation mark ( " " ) is missing.

    • let variableName = "Varable-Value;" // Right Syntax

      Eg:

       var placeName = "Cochin";

      Eg:

       var placeName = Brainchild; // Quotation mark ( " " ) is missing.

Slide 3

    • const variableName = "Varable-Value;" // Right Syntax

      Eg:

      Eg:

       var placeName = Cochin; // Quotation mark ( " " ) is missing.

 Const placeName = "Cochin"; 
 placeName = "Brainchild"; //cannot change the value of a constant.
