const testArr1 = ['pig', 'fox', 'zebra']
const testArr2 = ['ferrari', 'fox', 'pig', 'maserati']

// each value of a Set needs to be unique, so combining arrays that have 
// duplicate entries into a Set will auto-remove exact matches
const removeArrayDuplicates = (first, second) => {
    const combinedArrays = [...first, ...second];
    const arraySet = [...new Set(combinedArrays)]
    return arraySet

console.log(removeArrayDuplicates(testArr1, testArr2)
