In the next example, we remove 3 elements and replace them with the other two:

```js run
let arr = [*!*"I", "study", "JavaScript",*/!* "right", "now"];
let arr = [*!*"I'm", "studying", "JavaScript",*/!* "right", "now"];

// remove 3 first elements and replace them with another
arr.splice(0, 3, "Let's", "dance");

Here we can see that `splice` returns the array of removed elements:

```js run
let arr = [*!*"I", "study",*/!* "JavaScript", "right", "now"];
let arr = [*!*"I'm", "studying",*/!* "JavaScript", "right", "now"];

// remove 2 first elements
let removed = arr.splice(0, 2);

alert( removed ); // "I", "study" <-- array of removed elements
alert( removed ); // "I'm", "studying" <-- array of removed elements
```

The `splice` method is also able to insert the elements without any removals. For that, we need to set `deleteCount` to `0`:

```js run
let arr = ["I", "study", "JavaScript"];
let arr = ["I'm", "studying", "JavaScript"];

// from index 2
// delete 0
// then insert "complex" and "language"
arr.splice(2, 0, "complex", "language");

alert( arr ); // "I", "study", "complex", "language", "JavaScript"
alert( arr ); // "I'm", "studying", "complex", "language", "JavaScript"
```
