Warning
Do not create Boolean objects.
The new keyword complicates the code and slows down execution speed.
Boolean objects can produce unexpected results:
Booleans and boolean objects cannot be safely compared:
let x = Boolean(false);
let y = new Boolean(false);
(x == Y) returns true
(x === Y) returns false
Try it Yourself »
Comparing two JavaScript objects always return false.
