Differences between two operators

Double Equals (==) - It checks with only value of operands. It is type converting conversion, it will convert the operands into same type and then it will compare the values. 

 

Triple Equals (===) - It checks with value of operands and its datatype. It is Strict conversion, it wont perform any conversion when the operands are of different data types.

 

var a = 1;

var b = 1;

var c = "1";

console.log ( a == b ) ;          // return true

console.log ( a === b ) ;       // return true

console.log ( a == c ) ;         // return true

console.log ( a === c ) ;       // return false

hello Sonakshi,


its simple == checks only value whereas === checks valuse as well as Datatype

for e.g:-

  1=="1"  // is true

  but
  1==="1"  //is false.



Thanks,
