The Mozilla docs for "Primitive values" defines specifies six data types that are primitives:

• Number
• String
• Symbol (new in ECMAScript 6)

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

Everything else returns false:

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