Checks if the given number falls in the given range. Checks if the given number falls in the given range.
`end` is an optional parameter. If `end` is not given, the range is considered from `0` to `start`. Use arithmetic comparison to check if the given number is in the specified range.
If the second parameter, `end`, is not specified, the reange is considered to be from `0` to `start`.
```js ```js
const inRange = (n, start, end=null) => { const inRange = (n, start, end=null) => {
if(end && start > end) end = [start, start=end][0] if(end && start > end) end = [start, start=end][0];
return (end == null) ? (n>=0 && n<start) : (n>=start && n<end); return (end == null) ? (n>=0 && n<start) : (n>=start && n<end);
} }
// inRange(3, 2, 5) -> true // inRange(3, 2, 5) -> true
// inRange(3, 4) -> true // inRange(3, 4) -> true
// inRange(2, 3, 5) -> false // inRange(2, 3, 5) -> false
