array at js 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: java script arrays

fruits = ["Banana", "Orange", "Apple", "Mango"];
text = "<ul>";
for (i = 0; i < fruits.length; i++) {
  text += "<li>" + fruits[i] + "</li>";
}

Example 3: js arrays

// 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

Example 4: array in js

var array_name = [item1, item2, ...];      
//Used to store more than 1 items
