=== operator???

Question

I've seen this operator in a course recently, but I don't know what does it does exactly. Can you help?

Answer 1

a===b
Its an boolean operator that checks:
If a described a set, would b be a member of that set?

Answer 2

=== operator compares if two operands are of equal value and type. Unlike == which only tests for value.
10 == '10' #true
10 === '10' #false
I am not a ruby programmer but I guess it is the same in all languages
