### clampNumber
|
||||||
|
|
||||||
|
Clamps `num` within the inclusive `lower` and `upper` bounds.
|
||||||
|
|
||||||
|
If `lower` is greater than `upper`, swap them. If `num` falls within the range, return `num`. Otherwise return the nearest number in the range.
|
||||||
|
|
||||||
|
```js
|
||||||
|
const clampNumber = (num, lower, upper) => {
|
||||||
|
if(lower > upper) upper = [lower, lower = upper][0];
|
||||||
|
return (num>=lower && num<=upper) ? num : ((num < lower) ? lower : upper)
|
||||||
|
}
|
||||||
|
|
||||||
|
// clampNumber(2, 3, 5) -> 3
|
||||||
|
// clampNumber(1, -1, -5) -> -1
|
||||||
|
// clampNumber(3, 2, 4) -> 3
|
||||||
|
```
