<p>创建一个debounced函数该函数延迟调用fn直到自上次调用debounced函数后等待持续时间过去。</p>
<p>创建一个函数的去抖动版本。</p>
> ⚠️ 本函数已弃用. 使用 `Debounce` 代替.

### <span id="Debounce">Debounce</span>
<p>Creates a debounced version of the provided function. The debounced function will only invoke the original function after the specified delay has passed since the last time it was invoked. It also supports canceling the debounce.</p>
<b>Signature:</b>
```go
func Debounce(fn func(), delay time.Duration) (debouncedFn func(), cancelFn func())
```
<b>Example:</b>
```go
package main
import (
"fmt"
"github.com/duke-git/lancet/v2/function"
)
func main() {
callCount := 0
fn := func() {
callCount++
}

// Output:

### <span id="Debounced">Debounced</span>
<p>Creates a debounced function that delays invoking fn until after wait duration have elapsed since the last time the debounced function was invoked.</p>
