react === vs == 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: what is differ between between three equal and two equal

false == 0    =>  true
false === 0   =>  false

0 != false    =>  false
0 !== false   =>  true
