/**
|
|
* 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
