Answer
== compares values with type coercion.
=== compares value and type strictly. Prefer strict equality.
Quick Answer
== does loose equality with type coercion — "5" == 5 is true because JS converts the string to a number. === does strict equality with no coercion — "5" === 5 is false because types differ. Always use === in modern code to avoid the subtle bugs that type coercion introduces.
