TypeScript 3.7.5

Are you using TypeScript, but feel like you’re not making the most out of it? Do you find some advanced TypeScript concepts confusing? Do you get lost looking at complex type errors?

If you answered “yes” to any of these questions, then this course is for you! It introduces you to the world of advanced TypeScript concepts including: compiler flags for catching more errors, generic types, and how to compose types with discriminated unions. 

After finishing this course, you’ll feel more confident in your TypeScript skills. You will be able to write types that detect whole classes of possible runtime errors at compile time. Typing even the most untypeable JavaScript code will be a no brainer for you, and you’ll be fluent in TypeScript error messages.

## Introduction to state machines

Managing the state is one of the hardest parts of frontend development. Many frameworks and libraries have been created to help with this task. One of the proposed approaches is to utilize **state machines**. A state machine is a directed graph where nodes represent all possible states of a view or of the whole app, and where edges represent possible transitions between the states.
