I did this recently in JS and unusually, I’m sorry about it. Even given that I’m operating on an array and there can be occasional `undefined` (that is, missing array index) items, and I want to output a string result, surely there’s a better way to do this, right? Tell me.

let mask = [prevSet[a-1],prevSet[a],prevSet[a+1]].map((item)=>{ if(typeof item === 'undefined') return 0); else return item;}).join('');
```
