Difference between == and === in JavaScript

Question

*"I often see both == and === in JavaScript examples. What’s the actual difference between them? In which situations should I prefer one over the other? A clear example would really help!

Answer 1

== is equality, === is strict equality

== tries to convert the values in case they are of different types, while === does not try to convert.

Example:

"1" == 1 // true
"1" === 1 // false
