# --description--
You call curried functions like this:
```js
const result = add(1)(2);
```
Use `map` on the `charRange` in `addChars`, passing in `x => elemValue(n)(x)` as the argument.
# --hints--
See description above for instructions.
```js
assert(
code
.replace(/\s/g, '')
.includes(
'constaddChars=c1=>c2=>n=>charRange(c1,c2).map(x=>elemValue(n)(x))'
)
);
```
