Crafting Reliable and Testable Code with TypeScript

Explore the principles of crafting reliable and testable code using TypeScript in this 29-minute conference talk from the Reliable Web Summit 2021. Learn how to apply Agile Engineering Best practices to deliver scalable solutions for both front-end and back-end development. Discover the implementation of SOLID practices, OOP principles, and techniques to avoid over-engineering while writing testable code. Gain insights into high cohesion, low coupling, self-documenting code, and Test Driven Development. Understand the benefits of TypeScript for JavaScript at scale, and explore concepts such as interface segmentation, stateless code, and managing complexity. Delve into the FIRST principle, Mike Cohn's Testing Pyramid, and strategies for isolating dependencies to create more robust applications.
