Which equals operator (== vs ===) should be used in JavaScript comparisons? - Stack Overflow

The == operator compares the values of two variables after performing type conversion if necessary. On the other hand, the === operator compares the values of two variables without performing type conversion.

'' == '0'           // false

0 == ''             // true

0 == '0'            // true

'' == '0'           // false

0 == ''             // true

0 == '0'            // true

false == undefined  // false

false == null       // false

null == undefined   // true

"abc" == new String("abc")    // true

"abc" === new String("abc")   // false

Here the == operator is checking the values of the two objects and returning true

I prefer == here in this use case

true == 1; //true, because 'true' is converted to 1 and then compared

"2" == 2;  //true, because "2" is converted to 2 and then compared
