The document discusses the Angular framework for building single-page applications (SPAs), emphasizing a component-based architecture and unidirectional data flow for improved performance. It introduces tools such as NgRx for state management, TypeScript for static typing, and Webpack for module bundling. Recommendations include maintaining coding conventions and focusing on readability and testability to enhance developer experience.

- 7. Do events Repaint the DOMDo layout Recalculate the CSS Every time DOM changes, browser needs to TAKESTIME TRADITIONAL WAY
- 8. Modifies DOM when MODEL changed ANGULAR WAY 1 USE “1-WAY” Unidirectional Data Flow BATCH Update bindings, execute all changes COMPUTE minimal set of changes cause DOM to be updated RUN change detection on the Model 2 34 BETTER PERFORMANCE

- 17. Static type checker for JS strong/statically typed advantages Strong tool for LARGE app covers 100% of code catches incorrect assumptions e.g. numbers represented as strings Provides advanced autocompletion / intellisense navigation safe refactoring TypeScript #WhyTypeScript
- 18. My Recommendation project does not live for long project is really simple people enter or leave your team frequently there is a chance you will need to refactor the thing system is very important or even crucial for the success of company

- 27. Pros One framework to rule them all Full control/easy to manage coding flow Building reusable code/components Testable Readable Maintainable Performance Developer experience/community Server-side rendering => SEO Size is smaller after each release
- 28. Cons Learning curve Need to keepconventions/boilerplate Need to care aboutperformance All in One framework for small app
- 29. My Recommendation People are a part of solution Keep conventions / commitments Strategies for managing dependencies Take care about architecture and configurations Write small & pure functions as much as possible Write meaningful unit test as much as possible Don’t USE if you don’t NEED or UNDERSTAND it
