- Add `Chunk` to split slices into groups of size n. - Add `ContainsBy` for predicate-based containment checks. - Add `UniqueBy` to deduplicate slices by key selector. - Add `ParallelMap` for concurrent mapping with context and error handling. - Add `maps.Keys` and `maps.Values` helpers for extracting map keys/values. - Update README and docs for new features. - Refactor `Contains` to use `slices.Contains`.

`Map` produces a new slice of values by mapping each value in the slice through a
|
|
transform function.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
nums := []int{1, 2, 3}
|
|
toSquare := func(n int) int {
|
|
return n * n
|
|
}
|
|
fmt.Println(u.Map(nums, toSquare)) // {1, 4, 9}
|
|
}
|
|
```
