# @jridgewell/set-array
|
|
|
|
> Like a Set, but provides the index of the `key` in the backing array
|
|
|
|
This is designed to allow synchronizing a second array with the contents of the backing array, like
|
|
how in a sourcemap `sourcesContent[i]` is the source content associated with `source[i]`, and there
|
|
are never duplicates.
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
npm install @jridgewell/set-array
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
import { SetArray, get, put, pop } from '@jridgewell/set-array';
|
|
|
|
const sa = new SetArray();
|
|
|
|
let index = put(sa, 'first');
|
|
assert.strictEqual(index, 0);
|
|
|
|
index = put(sa, 'second');
|
|
assert.strictEqual(index, 1);
|
|
|
|
assert.deepEqual(sa.array, [ 'first', 'second' ]);
|
|
|
|
index = get(sa, 'first');
|
|
assert.strictEqual(index, 0);
|
|
|
|
pop(sa);
|
|
index = get(sa, 'second');
|
|
assert.strictEqual(index, undefined);
|
|
assert.deepEqual(sa.array, [ 'first' ]);
|
|
```
