# --description--
You can add more arguments by simply adding another arrow with another argument name:
```js
const manyArguments = a => b => c => d => [a, b, c, d]
```
Add another argument to `addChars` and add it to the sum: `c1 => c2 => n => c1 + c2 + n`.
# --hints--
See description above for instructions.
```js
assert(code.replace(/\s/g, '').includes('constaddChars=c1=>c2=>n=>c1+c2+n'));
```
