Let's say you checked it as follows ... var exists = haystack.includes( needle ); <exists> will be true when <haystack> has <needle> as one of its substring. If you want to inverse <exists> in JS log, you can simply use the unary logical NOT operator as follows, console.log ( !exists );

something like this? var someString = "just a random string"; var value = someString.includes("random") ? false : true; console.log(value); stored the inverse of includes() in another variable value OR just directly use the ternary operator where you wish to reverse the value
