Clamps `num` within the inclusive range specified by the boundary values `a` and `b`.
|
|
|
|
- If `num` falls within the range, return `num`.
|
|
- Otherwise, return the nearest number in the range.
|
|
|
|
```js
|
|
const clampNumber = (num, a, b) =>
|
|
Math.max(Math.min(num, Math.max(a, b)), Math.min(a, b));
|
|
```
|
|
|
|
```js
|
|
clampNumber(2, 3, 5); // 3
|
|
clampNumber(1, -1, -5); // -1
|
|
```
