### UUID generator
|
|
|
|
Use `crypto` API to generate a UUID, compliant with [RFC4122](https://www.ietf.org/rfc/rfc4122.txt) version 4.
|
|
|
|
```js
|
|
const uuidGenerator = () =>
|
|
([1e7] + -1e3 + -4e3 + -8e3 + -1e11).replace(/[018]/g, c =>
|
|
(c ^ crypto.getRandomValues(new Uint8Array(1))[0] & 15 >> c / 4).toString(16)
|
|
);
|
|
// uuid() -> '7982fcfe-5721-4632-bede-6000885be57d'
|
|
```
