Perhaps explicitly setting the types might do it? const x: number[]= [1,2] const y: number | undefined = x[666] const z: number = y + 3 EDIT: Just

Perhaps explicitly setting the types might do it?
const x: number[]= [1,2]
const y: number | undefined = x[666]
const z: number = y + 3
EDIT: Just tried, still works
- ht85 7y agoIt works because `undefined + number -> NaN`, and NaN is a number.
