type Arguments<T> = T extends (...args: infer A) => any ? A : never
type Return<T> = T extends (...args: any[]) => infer R ? R : never

function time<F extends Function>(fn: F, ...args: Arguments<F>): Return<F> {
  console.time()
  const result = fn(...args)
  console.timeEnd()
  return result
}

function time<F extends Function>(fn: F, ...args: Arguments<F>): Return<F> {
  console.time();
  const result = fn(...args);
  console.timeEnd();
  return result;
}

function add(a: number, b: number): number {
  return a + b;
}

const sum = time(add, 1, 2); // 调用 time 函数测量 add 函数的执行时间

console.log(sum); 
// 输出：
// [0.09ms] default
// 3

这一块的代码示例中，time 重复了，同学~
