What does the built in object hierarchy look like in javascript?

问题

I was looking for a diagram which shows the built in types of javascript like Function and String but on google I keep finding diagrams with the browser-related stuff like Window.

I'm just looking for the pure js object diagram. I know about the ECMA specification but I'm looking for a diagram because I'm a visual type.

回答1:

There's not much depth to the JavaScript types to speak of, the diagram would be fairly flat. It's basically (UML at the end):

primitive string
primitive number
primitive boolean
the Undefined type, which has exactly one instance: undefined
the Null type, which has exactly one instance: null
Symbol (a primitive type) (ES2015+)
Proxy (an object type, but one not backed by the default object prototype) (ES2015+)
Object
- Number
- String
- Boolean
- Function
- Date
- RegExp
- Array
- Math
- Error
  - EvalError
  - RangeError
  - ReferenceError
  - SyntaxError
  - TypeError
  - URIError
- JSON (ES5+)
- ArrayBuffer (ES2015+)
- DataView (ES2015+)
- The typed arrays (Int8Array, Uint8Array, Uint8ClampedArray, Int16Array, Uint16Array, Int32Array, Uint32Array, Float32Array, Float64Array) (ES2015+)
- Map (ES2015+)
- WeakMap (ES2015+)
- Set (ES2015+)
- WeakSet (ES2015+)
- Promise (ES2015+)
- Reflect (ES2015+)

So in UML, something like this:

Note that this is just JavaScript's type tree. It doesn't include lots of other things that are often used with JavaScript on browsers (such as the DOM, the worker's API, web storage, the File API, etc., etc.).
