    Three different scores: 44, 59, 19

  2. In all #WebPerf reporting tools with graphs, I would like to be able to quickly set a preferred scale, or ignore certain values that I know are incorrect.

  3. I needed a JavaScript way to verify if two arrays contain the same (all different) values.

    I then found a better solution for my use case, but it might be useful later, so here it is:

      array1.length === array2.length &&
      array1.every((element) => array2.includes(element));
