Discussion on: JavaScript: How to Remove Duplicate Values from Arrays

A similar function using Set is

function withoutDuplicates(inputArray) {
  const trackerSet=new Set();
  return inputArray.filter(
    v => !trackerSet.has(v) && trackerSet.add(v)
  ) // add returns the Set instance, which is truthy. You may wish to add a more explicit truthy return
}

These have the main advantage over Array.from(new Set(inputArray)) in that there's no need to iterate the Set after filling it with values, but I've done a little profiling and my snippet has pretty much the same characteristics and timing as Array.from(new Set(inputArray)) (just a little bit slower), even for very large arrays.

tbh, I think the big win is that they aren't leaning on JS Set's latent insertion-order stability, making the code more WYSIWYG, and more portable since in many other C-style languages Sets don't have that guarantee.
