How can I sort an array by segments in Javascript

Question

How can I sort:

[[{path:'a/b/c'}],[{path:'a/b'}],[{path:'a/b/c/d'}],[{path:'a/b'}]]

into this:

[[{path:'a/b'}],[{path:'a/b'}],[{path:'a/b/c'}],[{path:'a/b/c/d'}]]

I want to sort it by segment length. For example, a/b/c is three segments.

Answer 1

Use split and count the length of the output array.

Answer 2

 let toSort = [[{ path: 'a/b/c' }], [{ path: 'a/b' }], [{ path: 'a/b/c/d' }], [{ path: 'a/b' }]]; toSort.sort((a, b) => { return a[0].path.split('/').length - b[0].path.split('/').length }); console.log(toSort);
