Functions

func Keys

func Keys[M ~map[K]V, K comparable, V any](m M) []K

Keys 快捷提取所有key，不用写闭包

func Map

func Map[T, R any](src []T, fn func(T) R) []R

Map 处理切片 []T，单参数转换

func MapEntries

func MapEntries[M ~map[K]V, K comparable, V any, R any](m M, fn func(K, V) R) []R

MapEntries 遍历完整键值对 k+v

func MapKeys

func MapKeys[M ~map[K]V, K comparable, V any, R any](m M, fn func(K) R) []R

MapKeys 只遍历map key，对key做映射

func Reduce

func Reduce[T, R any](src []T, init R, fn func(R, T) R) R
