Can we simplify case sensitive?

Question

in example i have this code :

if (x == "one" || x == "One" || x == "ONE" || ..... ) {
// statements
}

is there any method or function or syntax so it's not necessary to type the case sensitive one by one? Thank you, Master

Answer 1

var a = input.value;
var b = a.value.toLowerCase();
