# --description--
Replace the body of `addChars`, so that instead of adding the arguments, it returns a `charRange` between the first two arguments: `c1 => c2 => n => charRange(c1, c2)`.
# --hints--
See description above for instructions.
```js
assert(
code.replace(/\s/g, '').includes('constaddChars=c1=>c2=>n=>charRange(c1,c2)')
);
