-# `String.random(options = { ... })` _(ext/string/random)_
-
-Returns generated random string, contained only of ascii cars `a-z` and `0-1`.
-By default returns string of length `10`.
-
-```javascript
-const random = require("ext/string/random");
-
-random(); // "upcfns0i4t"
-random({ length: 3 }); // "5tw"
-```
-
-## Supported options:
-
-### `isUnique: false`
-
-Ensures generated string is unique among ones already returned.
-
-_Note: When not applying this setting, accidental generation of same string is still highly unlikely. Provided option is just to provide a mean to eliminate possibility of an edge case of duplicate string being returned_
-
-### `length: 10`
-
-Desired length of result string
-
-### `charset: null`
-
-Fixed list of possible characters
-
-```javascript
-random({ charset: "abc" }); // "bacbccbbac"
-```
