Hello why This expands the relative paths to absolute paths?

[vaynevayne]

import { globSync } from 'glob';
import path from 'node:path';
import { fileURLToPath } from 'node:url';

export default {
	input: Object.fromEntries(
		globSync('src/**/*.js').map(file => [
			// This remove `src/` as well as the file extension from each
			// file, so e.g. src/nested/foo.js becomes nested/foo
			path.relative(
				'src',
				file.slice(0, file.length - path.extname(file).length)
			),
			// This expands the relative paths to absolute paths, so e.g.
			// src/nested/foo becomes /project/src/nested/foo.js
			fileURLToPath(new URL(file, import.meta.url))
		])
	),
	output: {
		format: 'es',
		dir: 'dist'
	}
};
