Coding guidelines

This document is split into three sections

On General Code Health. This section contains guidelines intended encourage patterns which produce more maintainable, less bug prone, code.
On Angular Best Practices. This section outlines the practices related to Angular, Typescript, RxJs and @ngrx/store. Following these general coding guidelines will help make the application cleaner.
On Angular Performance. This section contains guidelines intended to make an Angular app trigger change detection less often and on less entities.
