* Fix linting * Use is.ElementsMatch This will ignore the ordering of the final intersection. Especially important when checking old versions of go that do not guarantee an order when iterating through maps. * lint: fix inconsistent callback function parameter names * lint: rename "iteratee" to "transform" for *Map helpers * lint: rename "project" parameters to "transform" * lint: rename "cb" parameters to "callback" * lint: rename "iteratee" to "callback" for ForEach helpers --------- Co-authored-by: Franky W. <frankywahl@users.noreply.github.com> Co-authored-by: Samuel Berthe <dev@samuel-berthe.fr>

Iterates over elements of a collection and invokes the callback for each element in parallel.
|
|
|
|
```go
|
|
import (
|
|
"fmt"
|
|
lop "github.com/samber/lo/parallel"
|
|
)
|
|
|
|
lop.ForEach([]string{"hello", "world"}, func(x string, _ int) {
|
|
fmt.Println(x)
|
|
})
|
|
// prints lines in any order depending on scheduling
|
|
```
|
|
|
|
Useful for fire-and-forget work like publishing events or independent side effects:
|
|
|
|
```go
|
|
type Job struct{ ID int }
|
|
|
|
jobs := []Job{{1}, {2}, {3}}
|
|
lop.ForEach(jobs, func(j Job, _ int) {
|
|
// process each job concurrently
|
|
// send(j)
|
|
})
|
|
```
