# Map

Maps values of an array. Use `map_values` to map values of an object.

## Map array
Given a sample.yml file of:
```yaml
[1, 2, 3]
```
then
```bash
yq 'map(. + 1)' sample.yml
```
will output
```yaml
[2, 3, 4]
```

## Map object values
Given a sample.yml file of:
```yaml
{a: 1, b: 2, c: 3}
```
then
```bash
yq 'map_values(. + 1)' sample.yml
```
will output
```yaml
{a: 2, b: 3, c: 4}
```
