I have seen many places where angular js uses triple equals sign === to compare two elements why not 2 equals enter == . 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)
