Best 10 Code Snippets for Angular and TypeScript in 2022

What is a Code Snippet?

A Code Snippet is a block of code you can share and reuse. By reusing safe and proven code, you not only improve your productivity but you also make sure you always import the correct code and are not missing anything (e.g. missing argument, not checking error code or exceptions).

Why using Code Snippet for Angular & TypeScript?

Angular provides a comprehensive set of things that can help you build a robust application. Making applications with Angular + TypeScript combinations can be challenging. So, these code snippets can help you code faster and better.

1. Create a Component

#3 Use discriminated union instead of optional fields
