# Generate Random Integers
|
|
|
|
JavaScript's `Math` module has a built-in `random` function.
|
|
|
|
```javascript
|
|
> Math.random();
|
|
0.4663311937101857
|
|
```
|
|
|
|
It can be used to generate random floats between 0 and 1.
|
|
|
|
If you want integers, though, you're going to have to build your own function.
|
|
|
|
```javascript
|
|
function getRandomInt(max) {
|
|
return Math.floor(Math.random() * Math.floor(max));
|
|
}
|
|
|
|
> getRandomInt(10);
|
|
1
|
|
> getRandomInt(10);
|
|
7
|
|
> getRandomInt(10);
|
|
2
|
|
```
|
|
|
|
This function allows you to randomly generate numbers between `0` (inclusive)
|
|
and `max`, a number you specify (exclusive).
