arr javascript code example

Example 1: javascript array

//create an array like so:
var colors = ["red","blue","green"];

//you can loop through an array like this:
for (var i = 0; i < colors.length; i++) {
    console.log(colors[i]);
}

Example 2: javascript array

//An array is a list of thing, you can add as many things as you want

var food = ["cake", "apple", "Ice-Cream"]

//You can use Math.Random to pick a random number
//from one to the length of the array

var Number = [Math.floor(Math.random() * food.length)];
//then we can console.log the random word from the array
console.log(logammounts[woodloot])

Example 3: js array

var colors = [ "red", "orange", "yellow", "green", "blue" ]; //Array

console.log(colors); //Should give the whole array
console.log(colors[0]); //should say "red"
console.log(colors[1]); //should say "orange"
console.log(colors[4]); //should say "blue"

colors[4] = "dark blue" //changes "blue" value to "dark blue"
console.log(colors[4]); //should say "dark blue"
//I hope this helped :)

Example 4: access index of array javascript

let first = fruits[0]
// Apple

let last = fruits[fruits.length - 1]
// Banana
