Can anyone explain clearly about comparison operator '==='?

Answer 1

with a simple == you are testing values if they are equal but if you add one more = you check if the variable type is equal. for this reason 10=="10" is true but 10==="10" is wrong cause you are comparing an integer with a string.

Answer 2

That become usefull to compare types when you want to build a strict program, not wide open and ready to accept any type of input in a form for example.

Answer 3

Hi there.

=== means that the values you are comparing are identical.

Example: 3===4 is false. Because 4 is not 3.
3===3 is true. Because 3 is 3.

Do I answer your question?

Please let me know.
Good luck!
