# --description--
`evalFormula` is now pure, as it now has no external dependencies, and as before, performs no side effects.
Now define a new function, `increment` inside `spreadsheetFunctions`, which takes `nums` as argument and uses `map` to increment each value of `nums` by 1.
# --hints--
See description above for instructions.
```js
assert(JSON.stringify(spreadsheetFunctions.increment([1, 5, 3])) === '[2,6,4]');
```
