Bug: Handle Both Windows and UNIX Path Separators

[winner106]

Description:

The current SEP_NEGATE_RE regular expression only supports UNIX-style paths with the / separator. However, it fails to handle Windows-style paths, which use the \ separator. This bug causes the split function to incorrectly split Windows paths.

Steps to Reproduce:

1. Run the split function with a Windows path, for example:

   split("C:\\Users\\Administrator\\Documents\\KKNote\\Notes.md");
   

2. The function does not properly split the path and returns incorrect results.

Expected Behavior:

The split function should correctly handle both UNIX-style and Windows-style paths. It should split the path by both / and \ separators, and return the correct path components.

Solution:

• Modify the SEP_NEGATE_RE regular expression to handle both / and \ as valid path separators:

  const SEP_NEGATE_RE = /[^\\/]+/g;
  

• This change will allow the function to split paths with either separator.

Example:

For the input path C:\\Users\\Administrator\\Documents\\KKNote\\Notes.md, the expected output should be:

[
  "C:",
  "Users",
  "Administrator",
  "Documents",
  "KKNote",
  "Notes.md"
]
