How to recognise when we need the use of await keyword

async function onSubmit() {
  const url = "https://pokeapi.co/api/v2/ability/?limit=5&offset=5";
  try {
    const response = await fetch(url);
    if (!response.ok) {
      throw new Error(`Request unsuccessful, status code: ${response.status}`);
    }
    const result = await response.json();
    console.log(result);
  } catch (error) {
    console.error(error);
  }
}
