Combine and deduplicate Arrays

mergeDedupeArrays.js

// Note: Does only work with primities (numbers, strings) as objects/arrays, etc are saved by reference
// meaning even if the object is the same twice, the reference will be different and Set() will not have unique true values
// this could maybe be fixed by JSON.stringifying non-primitive values on save
export function mergeDedupeArrays(arrays) {
  let combinedArrays = []

  for (let array of arrays) {
    combinedArrays = combinedArrays.concat(array)
  }
  return [...new Set(combinedArrays)]
