true

All of the following return true:

console.log(isPrimitive(false));
console.log(isPrimitive(true));
console.log(isPrimitive(null));
console.log(isPrimitive());
console.log(isPrimitive(42));
console.log(isPrimitive('abc'));
console.log(isPrimitive(Symbol()));
//=> true

false

Everything else returns false:

console.log(isPrimitive({}));
console.log(isPrimitive([]));
console.log(isPrimitive(function(){}));
console.log(isPrimitive(new Date()));
// et cetera...
//=> false
