## Generate Random Whole Numbers with JavaScript
|
|||
|
|
|||
|
Here’s the setup:
|
|||
|
|
|||
|
```javascript
|
|||
|
var randomNumberBetween0and19 = Math.floor(Math.random() * 20);
|
|||
|
|
|||
|
function randomWholeNum() {
|
|||
|
|
|||
|
// Only change code below this line.
|
|||
|
Math.floor(Math.random() * 10);
|
|||
|
return Math.floor(Math.random());
|
|||
|
}
|
|||
|
```
|
|||
|
|
|||
|
We need to use ```Math.floor()``` with ```Math.random()``` to generate and return a random whole number between 0 and 9.
|
|||
|
Putting ```Math.floor()``` and ```Math.random()``` together, this is what our code looks like:
|
|||
|
|
|||
|
```javascript
|
|||
|
Math.floor(Math.random() * 10);
|
|||
|
```
|
|||
|
|
|||
|
And we need change the value of ```return```:
|
|||
|
|
|||
|
```javascript
|
|||
|
return Math.floor(Math.random());
|
|||
|
```
|
|||
|
|
|||
|
Here’s a full solution:
|
|||
|
|
|||
|
```javascript
|
|||
|
var randomNumberBetween0and19 = Math.floor(Math.random() * 20);
|
|||
|
|
|||
|
function randomWholeNum() {
|
|||
|
// Only change code below this line.
|
|||
|
return Math.floor(Math.random()*10);
|
|||
|
}
|
|||
|
```
