The problem is that when the type is inferred, then the type of o is: That’s not the same as { dic: { [name: string]: number } }. Critically, with the top signature you’re not allowed to do something like o.dic[‘x’] = 1. With the 2nd signature you are. They are equivalent types at runtime (indeed, they’re the exact … Read more
You can use IIFE (Immediately Invoked Function Expression) and function recursion instead. Like this: Live fiddle here.
The solution for me was to convert my code from using CommonJS (require, module.exports, etc) to ES Modules (import, export, etc.) The TypeScript documentation also appears to recommend ES Module syntax: TypeScript Modules Of course there’s a lot more to it than this, but as a start: Replace instances of require with import, e.g. Replace: … Read more
