On top of the growing collection of "must-know" tools in a web developer's arsenal is the famous (or maybe infamous?) TypeScript - a high-level programming language that adds static typing with optional type annotations to JavaScript. Developed by Microsoft, TypeScript can improve the developer experience by allowing the data that is passed around the code to be typed to something specific (ie Boolean), with TypeScript ready to throw an error if the types don't match appropriately through the program. In this episode, Matt and Mike discuss TypeScript at length discussing whether you need to learn TypeScript and how to learn it whether you're a beginner, or veteran coder.
