why axios in bootstrap.js?

Hello guys, I am new to Laravel. I installed laravel 10, and by default app.js is importing bootstrap.js, and bootstrap.js is importing axios. I am not using any node library, just php and alpine js. Do I still need axios? or axios is helpful in any other way if I am not using node js.

import axios from 'axios';

window.axios = axios;

window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
