Code Review: Where Code Meets People

When I first started considering learning how to program, I asked a developer friend “what if I contribute some code and unwittingly break something?” The response was “there should be a process in place to prevent that type of thing from happening.” Makes sense. Most fields have some form of this practice: QA, copy editing, fact-checking, and the list goes on. For development, that process is called code review.

Angular 5: Observable Basics

After working through the Tour of Heroes tutorial in the Angular 5 docs, I wanted to better understand a concept that was new to me: Observable.

React Redux Final Project Recap: Greenthumb Gardens

For my final project, I built an application with a React/Redux frontend and a Rails backend. I created Greenthumb Gardens, which is an app that allows users to search community gardens in NYC and update and view the plants that can be found at each garden.

For this project, I was required to add dynamic features that are possible only through jQuery and a JSON API to my previous Rails app, Socratic. After working through the requirements, I had some class-specific logic that was cluttering my JS files AKA spaghetti code. To clean things up, I moved this logic into the class files by using static methods.
