I have seen many places where angular js uses triple equals sign === to compare two elements why not 2 equals
== . I am just wondering is there any specific reason for that ?

The === operator checks value and type while the == operator only checks value, simple example
1 == "1" -> true
1 === "1" -> false (types are not equal)
Sometimes you want to use this strict comparison, especially when checking a boolean value.
1 == true -> true
1 === true -> false (types are not equal)
