💻 Code
type Item = {
a: {
b: 2;
c: boolean;
};
d: {
e: 3
}
f: 1;
}
type GetKeys<T> = {
[K in keyof T]: [K, ...(T[K] extends object ? GetKeys<T[K]> : [])]
}[keyof T]
type To<T> = {
index: GetKeys<T>; // Looking forward to ['a', 'b'] | ['a', 'c'] | ['d', 'e'] | ['f']
}
const obj: To<Item> = {
index: ['d', 'e'], // Parameter 2 Prompt b | c | e | f Expected to prompt e
}
🙁 Actual behavior
obj.index Parameter 2 Prompt b | c | e | f
🙂 Expected behavior
Expected to prompt e
