Typescript interface for object with arbitrary keys? [duplicate]

Question

I have an object that looks like this

{
  "sdfsdkhdfs": 1,
  "jjgtusdf": 2
}

where the keys are randomly generated, and there's an unspecified number of them. I want to create a type for this object in Typescript. How should I do this?

I think that Record<string, number> is what you need in this case. it just defines a Record with keys of type string and values of type number — Liad

The best you can do here is Record<string, number>.
