# ECMAScript proposal: @Name
# ECMAScript proposal: Readonly Arays and Objects
- [Motivation](#motivation)

## Motivation

Proposal motivation
Sometimes to prevent object and array changes we should to use `Object.freeze`, but the method very slow, so i propose readonly structure which will be constant by default

## High-level API

```js
// example code
const USER_STATUSES = new ReadOnly([
"banned",
"active",
"deleted"
]);

USER_STATUS[0] = "something" // Throw type error
```
