+```go
+func ExampleNew() {
+	var counter uint64
+
+	f := func() {
+		atomic.AddUint64(&counter, 1)
+	}
+
+	debounced := debounce.New(100 * time.Millisecond)
+
+	for i := 0; i < 3; i++ {
+		for j := 0; j < 10; j++ {
+			debounced(f)
+		}
+
+		time.Sleep(200 * time.Millisecond)
+	}
+
+	c := int(atomic.LoadUint64(&counter))
+
+	fmt.Println("Counter is", c)
+	// Output: Counter is 3
