Understand JavaScript Array Methods By Rebuilding Them From Scratch

Learn How to Create an Array Class!

In life, one of the best ways to learn is through doing. JavaScript is no exception, as many concepts may seem mystifying until you learn the underlying mechanics. The abstract nature of enumerable methods (map, filter and reduce), object construction, and the prototypical nature of JavaScript objects can confuse novice programmers. Let’s clear up some of that confusion by creating an Array class.

class OurArray {
    constructor() {
        this.items = []
        this.count = this.items.length
        if (arguments.length != 0) this.create_array(arguments)

    create_array(items) {
      for(let x = 0; arguments[0].length > x; x++) {

    push(element) {
        this.items[this.count] = element
        console.log(`${element} added to ${this.count}`)
        this.count += 1
        return this.count - 1

Learning JavaScript: Data Types and Variables

To paraphrase the title of an old computer science textbook, “Algorithms + Data = Programs.” The first step in learning a programming language such as JavaScript is to learn what types of data the language can work with. The second step is to learn how to store that data in variables. In this article I’ll discuss the different types of data you can work with in a JavaScript program and how to create and use variables to store and manipulate that data.
