Find duplicate names within an array of different files

A bit of a different use case from the ones I was suggested above. I need to loop through and check each file name within an array of files and push the files that have the same name into a new array so that I can upload them later separately.

This is my code so far, and surely I have a problem with my conditional checking, can somebody see what I am doing wrong?

filesForStorage = [
{id: 12323, name: 'name', ...},
{id: 3123, name: 'abc', ...},
{id: 3213, name: 'name', ...},
...
]

    filesForStorage.map((image, index) => {
          for (let i = 0; i < filesForStorage.length; i++) {
            for (let j = 0; j < filesForStorage.length; j++) {
              if (
                filesForStorage[i].name.split(".", 1) ===.   //.split('.', 1) is to not keep in consideration the file extension
                filesForStorage[j].name.split(".", 1)
              ) {
                console.log(
                  "----FILES HAVE THE SAME NAME " +
                    filesForStorage[i] +
                    " " +
                    filesForStorage[j]
                );
              }
            }
          }
