How to remove an array element returned by a function?

Question

typescript

Good afternoon, there is a function that returns a promise with an array of numbers.

How to remove an element from the result in an async function without additional variables?

async function a(): Promise<number[]> {
  return [1, 2, 3];
}

async function b(): Promise<void> {
  const tmp = await a();
  const result = tmp.shift();
  // что-то с result
}

I'm sure there is some simple solution that flew out of my head

Answer 1

async function a(): Promise<number[]> {
  return [1, 2, 3];
}

async function b(): Promise<void> {
  const [shift, ...result] = await a();
  // что-то с result
}
