Create a function to be able to add, substract, multiply or divide all the numbers given in the array provided.
Parameters:
1. Array
2. Operator:
-'Add'
-'Substract'
-'Divide'
-'Multiply'
Example:
function: getResult(array, operator)
array: [4, 2, 1]
operator: 'Add'
result: 7
operator: 'Substract'
result: 1
operator: 'Divide'
result: 2
operator: 'Multiply'
result: 8
function getResult(array, operator) {
