💻 Code
// Your code here
// Like this, but not same as this.
// For details, see the error reporting function of the error stack.
type Digits = '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9';
type T1 = `${Digits}${Digits}${Digits}${Digits}` | undefined;
type T2 = { a: string } | { b: number };
export function f1(x: T1 | null, y: T1 & T2) {
x = y; // Excessive complexity error
}
// Or like this
type Digits = '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9';
type T9XXXX = `9${Digits}${Digits}${Digits}${Digits}`;
type TXXXXX = `${Exclude<Digits, '0'>}${Digits}${Digits}${Digits}${Digits}`;
let x: Exclude<TXXXXX, T9XXXX> = '88888';🙁 Actual behavior
The error stack information is as follows:
