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`.
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)
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
```
```js
clampNumber(2, 3, 5) -> 3
clampNumber(1, -1, -5) -> -1
clampNumber(3, 2, 4) -> 3
```
