# How to check if an array includes a value

To easily know if an array includes a value we can use the **includes()** method:
```js
let items = [ "Computer", "Monitor" ];

items.includes("computer"); // false

items.includes("Computer"); // true
```

As you can see **it is case sensitive**. And you can check for example numbers too:
```js
let numbers = [ 4, 10, 27 ];

numbers.includes(2); // false

numbers.includes(10); // true
```

**It will return true if the value is found** within the array **or false if it's not**.
