The `ForEach` function allows for quickly iterating through an object or array.
The key and value are passed to the iterator function for objects.
Only the value is passed for arrays.
With an array the key is an index and the value is passed.
Returning `false` from an iterator will stop iteration.
```go
result := gjson.Get(json, "programmers")
result.ForEach(func(key, value gjson.Result) bool {
println(value.String())
println(key.Int()) // index of the array
println(value.String())
return true // keep iterating
})
```
