A little-bit of ReGex
The line `path.split(/\/+/);` is a JavaScript expression that splits a string `path` into an array of substrings using one or more forward slashes (`/`) as the separator.
Here's a breakdown:
- `path`: This is the string variable that contains the path to be split.
- `split()`: This is a string method that splits a string into an array of substrings based on a specified separator.
- `/\/+/`: This is a regular expression that matches one or more forward slashes (`/`). The `/` characters are escaped with a backslash (`\`) because `/` has a special meaning in regular expressions. The `+` quantifier matches one or more occurrences of the preceding pattern.
When you call `path.split(/\/+/)`, the string is split into an array of substrings at each occurrence of one or more forward slashes. Any consecutive forward slashes are treated as a single separator.
Here are some examples:
- `path = "a/b/c"` would result in `["a", "b", "c"]`
- `path = "a//b/c"` would result in `["a", "b", "c"]`
- `path = "/a/b/c/"` would result in `["", "a", "b", "c", ""]`
Note that if the path starts or ends with a forward slash, you may get empty strings in the resulting array. If you want to remove these empty strings, you can use the `filter()` method:
path.split(/\/+/).filter(Boolean);
This would remove any empty strings from the array.
