array methods

1//create an array like so:
2var colors = ["red","blue","green"];
3
4//you can loop through an array like this:
5for (var i = 0; i < colors.length; i++) {
6    console.log(colors[i]);
7}

1let fruits = ['Apple', 'Banana']
2
3console.log(fruits.length)
4// 2

1var colors = [ "red", "orange", "yellow", "green", "blue" ]; //Array
2
3console.log(colors); //Should give the whole array
4console.log(colors[0]); //should say "red"
5console.log(colors[1]); //should say "orange"
6console.log(colors[4]); //should say "blue"
7
8colors[4] = "dark blue" //changes "blue" value to "dark blue"
9console.log(colors[4]); //should say "dark blue"
10//I hope this helped :)

1dogs.toString();                        // convert to string: results "Bulldog,Beagle,Labrador"
2dogs.join(" * ");                       // join: "Bulldog * Beagle * Labrador"
3dogs.pop();                             // remove last element
4dogs.push("Chihuahua");                 // add new element to the end
5dogs[dogs.length] = "Chihuahua";        // the same as push
6dogs.shift();                           // remove first element
7dogs.unshift("Chihuahua");              // add new element to the beginning
8delete dogs[0];                         // change element to undefined (not recommended)
9dogs.splice(2, 0, "Pug", "Boxer");      // add elements (where, how many to remove, element list)
10var animals = dogs.concat(cats,birds);  // join two arrays (dogs followed by cats and birds)
11dogs.slice(1,4);                        // elements from [1] to [4-1]
12dogs.sort();                            // sort string alphabetically
13dogs.reverse();                         // sort string in descending order
14x.sort(function(a, b){return a - b});   // numeric sort
15x.sort(function(a, b){return b - a});   // numeric descending sort
16highest = x[0];                         // first item in sorted array is the lowest (or highest) value
17x.sort(function(a, b){return 0.5 - Math.random()});     // random order sort
