- "func MaxBy[T any](collection []T, comparison func(a T, b T) bool) T"
|
|
---
|
|
|
|
Searches the maximum value of a collection using the given comparison function. Returns zero value when the collection is empty.
|
|
|
|
```go
|
|
type Point struct{ X int }
|
|
max := lo.MaxBy([]Point{{1}, {5}, {3}}, func(a, b Point) bool {
|
|
return a.X > b.X
|
|
})
|
|
// {5}
|
|
```
|
|
|
|
Note: the comparison function is inconsistent with most languages, since we use the opposite of the usual convention.
