Developing logic-rich applications is a key skill to have.
The TypeScript-React combination helps you unlock that skill, and it’s a great developer experience in terms of writing understandable and refactorable HTML. But the default state management for React has a long way to go to feel simple and maintainable – and that’s where MobX makes your life so much easier.

In this course, we will go through the concept of transducers and build them up from basic principles. We will go over the problems with regular composed transformations, and show how we end up with unnecessary data and intermediate collections. We go on to learn how we can use transducers for performance gains when operating on large data sets, as well as how they’re an excellent fit for processing other iterable data, like generators. Not just arrays.
