Polymorphism does not have to be a scary word — Abstraction, encapsulation, inheritance, and polymorphism are the four pillars on which object oriented programming (OOP) is built. Following these principles will lead to clean, reusable, and modular code but your first need to understand what they mean. …

A large part of programming is writing tests to make sure your code works as expected. On smaller projects writing tests can seem cumbersome but they will show their value as features are added, modules are refactored, and the team grows. Most software engineers are familiar with the basic testing…

Git is an extremely useful tool that has become almost ubiquitous with programming itself. Unfortunately, learning it can be a bit overwhelming with the seeming endless git documentation. Eventually everyone masters manipulating and merging branches on small projects but as repositories grow in size as well as contributors things can…

Now, I normally slice through the whole stack and eat a bit from each pancake at once but lets pretend, for the sake of this discussion, that I am a reasonable person that…

Data Structures in JavaScript — In the previous “Data Structures in JavaScript” discussion, we walked through the methodology used to construct a node class which represent each “link” in the “chain” that is a linked list. From there we discussed how to construct a singly linked list from a an array. Building on the previous…

Data Structures in JavaScript — Most likely you arrived at this article because your preparation for an interview has lead you down a LeetCode rabbit hole. Linked lists are a favorite of many interviewers to test an interviewees understanding of basic data structures as well as your problem solving skills. …
