Reference

link(fs, rewrites)

rewrites is a 2-tuple or an array of 2-tuples, where each 2-tuple has a form of [from, to]. from is the new, virtual path; and to is an existing path in the fs filesystem.

const lfs = link(fs, ['/foo', '/bar']);

or

const lfs = link(fs, [
    ['/foo1', '/bar1'],
    ['/foo2', '/bar2'],
    ['/foo3', '/bar3'],
]);
