CET @shaedrich@mastodon.online#TypeScript devs: I have the following class, emitting the type error below. How is it that TS isn't able to infer the type of the props correctly and how can I make it?
![class MyClass {
readonly key: string | number | boolean
readonly value: string | number | boolean
constructor(key: string | number | boolean, value: string | number | boolean | undefined) {
this.key = key
this.value = value ?? key
}
}
enum MyEnum {
A = 1,
B = 2,
}
const myInstance = new MyClass('A', 'a')
const myIndex = MyEnum[myInstance.key]
