/** | |
* Parse a path string into an array of path segments. | |
* | |
* Square bracket notation `a[b]` may be used to "escape" dots that would otherwise be interpreted as path separators. | |
* | |
* Example: | |
* a -> ['a'] | |
* a.b.c -> ['a', 'b', 'c'] | |
* a[b].c -> ['a', 'b', 'c'] | |
* a[b.c].e.f -> ['a', 'b.c', 'e', 'f'] | |
* a[b][c][d] -> ['a', 'b', 'c', 'd'] | |
* | |
* @param {string|string[]} path | |
