How is "===" working with object and why should we use it?

Question

This "===" sign has been puzzling me for long, and I am wondering how it works with object (with multiple properties) and when to use it. Why not use a simple "=="?

Answer 1

tests for type and value and results to true if type AND value matches.

Answer 2

In addition to the other answer, if you want to save yourself the hassle - just use == instead of === for checking if something is equal without worrying about it being equal in both type and value
