What it reports

async function with no await at line {line}. The async keyword only wraps the return value in a Promise here; drop it or await something.

Flagged

async function load() {
  return cached;
}

async function load(pending: Promise<Item>) {
  return pending;
}

Not flagged

async function load() {
  return await fetchIt();
}

async function load(): Promise<Item[]> {
  return cached;
}

class Provider {
  async getChildren(element?: Node): Promise<Node[]> {
    return [];
  }
}

const parse = async (text: string): Promise<number> => Number(text);

const props = { onToggle: async () => ({ enabled: true }) };

function load() {
  return cached;
}

const spy = vi.fn(async (name) => undefined);
