Is there any way to push elements from array2 if array1 doesn't include them already, without using a for loop iterating each element?
Ex:
array1 = [1, 2, 3]
array2 = [1, 3, 5, 6]
So my result want to be this:
array1 = [1, 2, 3, 5, 6]

array1 = [1, 2, 3]
array2 = [1, 3, 5, 6]
// Use set to remove duplicates, concat to merge the two arrays
result = [...new Set(array1.concat(array2))]
console.log(result)Remove duplicates
