What is the difference between identical(===) and equal(==)?

Any and all help appreciated!

Hi Aysha, I had hard time with this myself until I fully understood what is about... Identical has to be identical (exactly the same), for ex. 3===3 or "3"==="3" (as a string) would evaluate as true, but "3" is not identical with 3, because one is a string, one is a number. Equal is way more forgiving, meaning "3" == 3 would evaluate true, however one is a string (in between quotes) and the other is a number. I hope this helped!

If they are identical they will be the same data type whereas with equal the data type doesn't make much of a difference.

I hope this helped you out! If you have any more questions feel free to ask!
