### 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
|
|
```
