Need a basename function in Javascript

Question

I need a short basename function (one-liner ?) for Javascript:

basename(\"/a/folder/file.a.ext\") -> \"file.a\"
basename(\"/a/folder/file.ext\") -> \"f         


        

Answer 1

JavaScript Functions for basename and also dirname:

function basename(path) {
     return path.replace(/.*\//, '');
}

function dirname(path) {
     return path.match(/.*\//);
}

Sample:

Input                       dirname()           basename()
/folder/subfolder/file.ext  /folder/subfolder/  file.ext
/folder/subfolder           /folder/            subfolder
/file.ext                   file.ext            /
file.ext                    file.ext            null
