Triple bar

A triple bar is a symbol that looks like 3 equals signs next to each other (===). It is used in computer programming to test if two things are exactly the same. Kind of like how you need to make sure your legos fit exactly to build a castle, programmers need to make sure things are exactly the same to make their program work correctly. The triple bar helps them do this by comparing two things and only saying they are the same if they are exactly the same, nothing more or less!
