Difference between 2 axios calls in a mounted hook in Vue

Hello,

Would anyone knows the difference between these 2 axios calls in a mounted hook(Vue). First version

let endpoints = [
  'https://api.github.com/users/ejirocodes',
  'https://api.github.com/users/ejirocodes/repos',
  'https://api.github.com/users/ejirocodes/followers',
  'https://api.github.com/users/ejirocodes/following'
];

axios.all(endpoints.map((endpoint) => axios.get(endpoint))).then(
  (data) => console.log(data),
);

second version

  axios.all([
                this.method1(),
                this.method2(),
                this.method3(),
                this.method4(),
            ]).then(axios.spread((...responses) => {
            })).catch((errors) => {
                console.log("Dropdowns and Listing Details not all loaded!");
            });

Are they not both calling each method concurrently?

Any cases where you should use one compared to the other please?

Thank
