Return the relative path from one path to another
npm install get-relative-path
Work out what the relative path to get from from to to is.
i.e. Starting at from, what path would lead us to to.
Similar to Node.js's path.relative()
but works outside the context of a filesystem, and assumes
all paths are POSIX-style.
So this also works for URL pathnames.
```
npm install get-relative-path
`js
const getRelativePath = require('get-relative-path');
console.log(getRelativePath('/data/orandea/test/aaa/', '/data/orandea/impl/bbb'));
// ../../impl/bbb
console.log(getRelativePath('data/orandea/test/aaa/', 'data/orandea/impl/bbb'));
// ../../impl/bbb
console.log(getRelativePath(
new URL('https://localhost/data/orandea/test/aaa/').pathname,
new URL('https://localhost/data/orandea/impl/bbb').pathname
))
// ../../impl/bbb
