Javascript “===” and “==” operator

“==” operator uses type coersion.
“===” operator checks type and value.

Always use “===” operator. “==” operator is a bug in the language.

1 == 1 : true
1 === 1 : true
“1” == 1 : true
“1” === 1 : false

obj1 === obj2 : true, if both variables refer to the same object.
