Object.keys() as const not working. How can I achieve this? (Suppose I don't know the content of the object, I don't know what keys does my object have)

const values = Object.keys(myObject) as const;

I need the as const to get string literal types

let name: typeof values[number];

• javascript
• typescript
• typeof

• why are you using as ... it should know what that is automatically. – Get Off My Lawn Commented Jan 20, 2021 at 17:26

You can do

let name: keyof typeof myObject

See this question for why strongly typing Object.keys might be a bad idea.
