There is a list of keys can be enum, array anything like keys = ["x","y","z"]
Need to implement an interface which can have key from this array
something like:
interface Points {
[index: keys]: string
}
But this doesn't work as index can only be string or number.
What is better way to achieve this?
If they keys are known at compile-time you could do something like this:
type Keys = 'x' | 'y' | 'z';
type Points = {
[key in Keys]: string;
}
This will require a Point record to have all the keys. You can make them optional with [key in Keys]?: string.
If the keys are not known at compile-time, you can't really type check it with Typescript can you ;)
