When declaring a variable we have two parts they are data type and value
var age = 18; // dataType = number, value = 18So == operator only compare value and === compare both value and datatype
var age = 18; // dataType = number, value = 18 var myAge = "18"; // dataType = string, value = 18 age == myAge; // True age === myAge // FalseSandeep Kumar Apr 03 2020
