- How do I detect if a user is already logged in Firebase?
common Firebase pitfalls, following JS code,
- Mastering asynchronous code execution is fundamental to becoming a great TypeScript developer.
- In this course we show how TypeScript enables you to write asynchronous code with complete type safety and great runtime support thanks to TypeScripts understanding of the async / await pattern.
- In this course we will cover concepts like Promises, generators and how they enable the runtime environment to allow authoring asynchronous code just as beautifully as synchronous code.
- TypeScript, as the superset of JS uses compile-time type checkings with latest specification standard and proposals.
- I want to show that with TypeScript you will be more productive no matter what front end technology you use.
- What are the most common Firebase pitfalls and gotchas?
