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