What's difference in use between == and ===?

Answer 1

== will return true if (5=5) or (5="5")
=== will return true if (5===5) but will return false if (5==="5") becoz 5 is a integer and "5" is string. they are equal but are not of same type.
=== is strict compression operator.

Answer 2

"==" will return the argument to be true if another object have the same property or value while "===" will return an argument to be true if more than one object is being compared with the first operand.

Answer 3

== defines only same value..But === defines not only same value but also same data type

Answer 4

5=='5' will return true
5==='5' will return false

Answer 5

one represents "equal". one represents "identical".
