null == undefined // true
null === undefined // false
'0' == false // true
'0' === false // false!= vs !== javascript
(0 == '0') // true
(0 === '0') // false
('' == 0 ) // true, the string will implicitly be converted to an integer

/**
* In js :
* == it convert the variable values to the same data type before performing comparison.
* example : comparison between string and interger data type
*/
(5 == "5") // returns true
// === it does not convert data type of variable before performing comparison.
// example:
(5 === "5") // return false== vs === javascript
== Equal to (1 == 1, 1 == "1") // equal in value ("1" is a string)
=== Equal value and equal type (1 === 1 but, 1 !== "1" // not equal typeCopyright © 2021 Codeinu
