Write a snippet of code using at least one of the following es6 features: Object destructuring, arrow functions, let, template strings

Write a function getMax that returns the max element of an array of positive integers such as:

getMax([1, 4, 3, 2]); // returns `4`

Write the sum function using recursion such as:

sum(0); // returns 0
sum(1); // returns 1 (= 1 + 0)
sum(2); // returns 3 (= 2 + 1)

var out = 1;

var doMoreStuff = function() {
  if (!out) {
    var out = 2;
  }
  console.log(out);
};

doMoreStuff();
