Clamps `num` within the inclusive `lower` and `upper` bounds. 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. 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 ```js
const clampNumber = (num, lower, upper) => { const clampNumber = (num, lower, upper) => {
if(lower > upper) upper = [lower, lower = upper][0]; 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(2, 3, 5) -> 3
