Core Newdebounceby - Lo

Creates a debounced function per key that delays invoking callbacks until after the wait duration has elapsed for that key. Returns a per-key debounced function and a per-key cancel function.

debounce, cancel := lo.NewDebounceBy[string](
    100*time.Millisecond,
    func(key string, count int) {
        println(key, count)
    },
)

for i := 0; i < 10; i++ {
    debounce("first")
}

time.Sleep(200 * time.Millisecond)
cancel("first")
