In the second part of our look at Singly Linked Lists, we created a .shift() instance method.

In today’s article, we’ll be exploring how to add an .unshift() function to our Singly Linked List class.

Let’s Unshift Gears

Here’s the pseudocode:

• The function should accept a value
• Create a new node using the value passed to the function
• If there is no head property on the list, set…

In the second part of our look at Singly Linked Lists, we created a .pop() instance method, a method common in other structures like Arrays.

In today’s article, we’ll be exploring how to add a .shift() function to our Singly Linked List class.

Let’s Shift Gears

In arrays, .shift() removes the first element of the array. While the goal is the same, its implementation with our Singly Linked List is slightly…

In today’s article, we’ll be exploring how to add a .pop() function to our Singly Linked List class.

Previously on Data Structures Decoded…

In the first part of our look at Singly Linked Lists, we examined how we can use the Class syntax to create a Singly Linked List class. In it, we created a .push() instance method, a method common in other structures like Arrays.

.Pop() Goes The Weasel

So, creating .pop() functionality isn’t as straightforward…

In today’s article, we’ll be exploring the basics of a Singly Linked List.

What is it?

A linked list is a ordered data structure that stores any kind of data you’d like. It contains a head, a tail, and a length property. Linked lists consists of nodes and each node has a value and a pointer to another node or null.

A useful exercise to increase our understanding of a singly…

Today’s article is a special one: it marks the official start of our exploration of the subject!

What is it?

Let’s take a look at what a data structure is according to Wikipedia:

A data structure is a data organization, management, and storage format that enables efficient access and modification.[1][2][3]More …

Today, we’re wrapping up our exploration of Object Oriented Programming in Javascript.

Class Methods

In part one, I covered how Javascript handles Object Oriented Programming without actually being an OOP-based programming language. We covered classes, constructors, and instance method. Now, we’re diving a little more deeply into class methods.

What are they?

Also known as static methods, class methods are used only with entire classes rather than instances of that class. …

Today, we’re exploring using Object Oriented Programming in Javascript.

What is it?

Technically, Javascript doesn’t support OO programming but in 2015 introduced the Class syntax. A Class is a blueprint for creating objects with predefined properties and methods.

That’s cool, but why should I care?

We’ll be using the Class syntax to define data structures.

How does it work?

The class keyword creates a constant. (Keep in mind you cannot redefine it.) The method to create new objects must be called constructor and…

Today, we’re wrapping up our exploration of merge sort.

Previously on Algorithm Action…

In Part 1 of this series, we explored why we need a helper function to make merge sort work and defined it.

function merge(arr1, arr2){ 
    let results = []; 
    let i = 0; 
    let j = 0; 
    while (i < arr1.length && j <…
