While working on a project, I had the need to get the last segment of a path.
In this case it was a filesystem path, but this would work also for URLs.
const lastItem = thePath.substring(thePath.lastIndexOf('/') + 1)
How does this work?
thePath string contains a path. Like
/Users/Flavio/Desktop, for example.
We identify the index of the last
/ in the path, calling
lastIndexOf('/') on the
Then we pass that to the
substring() method we call on the same
This will return a new string that starts from the position of the last
/, + 1 (otherwise we’d also get the
Finally, we assign that string to
You can make a simple function for it, too:
const getLastItem = thePath => thePath.substring(thePath.lastIndexOf('/') + 1) getLastItem('/Users') getLastItem('/Users/Flavio') getLastItem('/Users/Flavio/test.jpg') getLastItem('https://flavicopes.com/test')
