// Making an array:
const colors = ["red", "orange", "yellow"];

// Arrays are indexed like strings:
colors[0]; // "red"

// They have a length:
colors.length; //3

// Important array methods:
//push(value) - adds value to the END of an array
//pop() - removes and returns last value in array

//unshift(val) - adds value to START of an array
//shift() - removes and returns first element in an array

//Creating a list
var fruits = ["Apple", "Banana", "Cherry"];

//Creating an empty list
var books = [];

//Getting element of list
//Lists are ordered using indexes
//The first element in an list has an index of 0, 
//the second an index of 1,
//the third an index of 2,
//and so on.
console.log(fruits[0]) //This prints the first element 
//in the list fruits, which in this case is "Apple"

//Adding to lists
fruits.push("Orange") //This will add orange to the end of the list "fruits"
fruits[1]="Blueberry" //The second element will be changed to Blueberry

//Removing from lists
fruits.splice(0, 1) //This will remove the first element,
//in this case Apple, from the list
fruits.splice(0, 2) //Will remove first and second element
//Splice goes from index of first argument to index of second argument (excluding second argument)
