Generates a random integer in the specified range.
|
|
|
|
- Use `Math.random()` to generate a random number and map it to the desired range.
|
|
- Use `Math.floor()` to make it an integer.
|
|
|
|
```js
|
|
const randomIntegerInRange = (min, max) =>
|
|
Math.floor(Math.random() * (max - min + 1)) + min;
|
|
```
|
|
|
|
```js
|
|
randomIntegerInRange(0, 5); // 2
|
|
```
