Test your concepts of arrays by determining the location of an item in an array.

const indexOf = (arr, item) => {
    // Your code here
}

indexOf([1,2,3,4], 3) => 2
indexOf([5,6,7,8], 8) => 3

const products = [
  {
    name: "fanny pack",
    price: "30",
    preOrder: "true",
  },
  {
    name: "beanie",

Implement a function that merges two sorted arrays into another sorted array. Name it mergeArrays(arr1, arr2)

Input: An array and a number value Output: An array with two integers a and b ([a,b]) that add up to value

Input
arr1 = [1,3,4,5]

O(n logn)

	function showItems(arg1, arg2, arg3) {
	var arr = [arg2, arg3].concat(arg1);
	console.log(arr);
	}
	showItems(["dogs", "cats"], "turtles", "sharks");

	const getLocation = (city, country = "Italy", continent = "Europe") =>
	console.log(continent, country, city);

	getLocation("Milan");
	// Europe Italy Milan

	getLocation("Paris", "France");
	// Europe France Paris

	const person = {
	first: "Alberto",
	last: "Montalesi",
	};

	const { first: firstName, last: lastName } = person;

	console.log(firstName, lastName); // console.log(firstName , lastName)

	// String Variable With Explicit Annotation
	let movieTitle: string = "Amadeus";
	movieTitle = "Arrival";
	movieTitle = 9; //This results in an error!
	movieTitle.toUpperCase();

	// Number Variable with explicit annotation
	let numCatLives: number = 9;
	numCatLives += 1;
	numCatLives = "zero"; //Error!

	const calculatePrice = ({ total, tax = 0.1, tip = 0.05 }) =>
	total + total * tax + total * tip;
