JavaScript
const mySet = new Set();

mySet.add(15);
mySet.add(33);
mySet.add(15);

for(let item of mySet) {
	console.log(item)
    // expected output: 15
	// expected output: 33
}const myArray = ['hello', 'world'];

// add an element to the end of the array
myArray.push('foo'); // ['hello', 'world', 'foo']

// add an element to the front of the array
myArray.unshift('bar'); // ['bar', 'hello', 'world', 'foo']

// add an element at an index of your choice
// the first value is the index you want to add at
// the second value is how many you want to delete (0 in this case)
// the third value is the value you want to insert
myArray.splice(2, 0, 'there'); // ['bar', 'hello', 'there', 'world', 'foo']//HOW TO ADD:
var num1 = 4;
var num2 = 6;
var answer = 4 + 6; //You can do num1 + num2 here!
function add(num1, num2) {
  return num1 + num2;
};
console.log("4 + 6 is: " + add());
console.log("I hope this helped!");
