difference == and === js code example

Example 1: difference between == and === in javascript

0 == false   // true
0 === false  // false, because they are of a different type
1 == "1"     // true, automatic type conversion for value only
1 === "1"    // false, because they are of a different type
null == undefined // true
null === undefined // false
'0' == false // true
'0' === false // false

Example 2: == 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 type
