# getType

Canonical: https://www.wiki.jodisand.me/snippets/javascript/gettype/


Returns the native type of a value.

- Return `'undefined'` or `'null'` if the value is `undefined` or `null`.
- Otherwise, use `Object.prototype.constructor.name` to get the name of the constructor.

```js
const getType = v =>
  (v === undefined ? 'undefined' : v === null ? 'null' : v.constructor.name);
```

```js
getType(new Set([1, 2, 3])); // 'Set'
```
