- **Kind:** method
- **Source:** https://github.com/libtmux/libtmux-ts/blob/073b9d7dedad900bff6f5ec0ea47794e40225870/packages/libtmux/src/selection.ts#L468

```
map<Result>(
  transform: (
    value: Model,
    index: number,
    values: readonly Model[],
  ) => Result,
  thisArg?: unknown,
): Result[]
```

Apply `transform` to each member, in order.

Returns an array rather than a Selection: the results are no longer tmux
objects, so they carry no identity to filter, count, or traverse from.

## Examples

```ts
snapshot.windows.map((entry) => entry.name); // string[]
```

## Type parameters

- `Result`
- [`Model`](/en/ts/latest/reference/selection-selection/#selection.Selection.type-parameter.Model), declared by [`Selection<Model>`](/en/ts/latest/reference/selection-selection/)

## Parameters

- `transform` (`(value: Model, index: number, values: readonly Model[]) => Result`)
- `thisArg?` (`unknown`)
