In JavaScript, is there a performance difference between using a double equals (==) vs using a triple equals (===)?
Example: if (foo == bar) vs if (foo === bar)
Strict comparison (
===) will always be slightly faster, but the difference is usually negligible.It definitely makes sense to prefer
===if you know for certain that you don’t need type coercion in the comparison. It will always be at least as fast as==.
