Equals operators (==) VS (===) - Javascript

equals_operators.md

• (==)(!=) (==)(!=) considers the value but not the type

Example :

0=='0'  //==> True

• (===)(!==) (===)(!==) considers the value AND the type

Example :

0==='0'  ==> False  

(==)(!=) does type coercion. It converts the value before comparing. Called "Loose equality" (===)(!==) doesn't convert. Called "Strict Equality"
