Love the level of documentation here, but check the specs for doc blocks. The `@param` and `@return` tags shouldn't have a colon afterwards, the first word after the tag is the Type, and the second word after the tag is the name of the variable. It's precise. Everything after that can describe the value, e.g.

```javascript
/**
  * The tick function...
  *
  * @param Array board of Array of Boolean for each cell
  * @param Array of Array of Boolean representing the next board
  */
```
