Flip
题目
Implement the type of just-flip-object
. Examples:
typescript
Flip<{ a: "x", b: "y", c: "z" }>; // {x: 'a', y: 'b', z: 'c'}
Flip<{ a: 1, b: 2, c: 3 }>; // {1: 'a', 2: 'b', 3: 'c'}
Flip<{ a: false, b: true }>; // {false: 'a', true: 'b'}
No need to support nested objects and values which cannot be object keys such as arrays
解答
ts
type Flip<T extends Record<string, string | number | boolean>> = {
[P in keyof T as `${T[P]}`]: P;
};
