Types are low level. JavaScript is very high on the stack, and has no concept of types, it only has "value objects" (variable values: string and number, plus static values: true, false, null, undefined) and "normal objects" (Array, Object, Date, Function, etc). There's a debate though on what type should be used for numeric values in JavaScript. In JavaScript you rarely see getters and setters, as you do not need any abstraction over the type system, although it is possible to do bitwise operations, so if you want to you could make your own types, although you will not have full control of their binary representation, witch you would need a "real" programming language with a proper type system, but I've only seen that in optimization witch rarely runs faster then native JS. You get a lot of productivity by not having to worry about types in JS, and you rarely se buffer overflows witch is common in lower level languages such as C and C++. JavaScript is an an abstraction where you do not have to worry about the under-layer like imperative memory management. If you have to decide between small int vs big int vs floats, it's a leaky abstraction. JavaScript is one level above that.
