Answer 2

The difference is:
two == are checking if value a is equal to value b

three === are checking type too so if values are equal for eg. both have value 5 then program will check if they are both int or double...

!= and !== are working on similar way they are just checking if values are different

Answer 3

== is the "equal to" operator which tests for equality while != is the "not equal to" operator while === and !== are comparison operators
