Angular JS: A Brief Introduction
1 like395 views
AngularJS is a structural framework designed for building dynamic web applications, emphasizing declarative code for user interface development. Key concepts include directives, two-way data binding, expressions, templating, and services, which facilitate enhanced functionality and organization in applications. It is particularly suited for single-page applications but may struggle with intensive DOM manipulations.
![Key Concepts - Expressions
Angular expressions are JavaScript-like code snippets that are usually placed in
bindings such as {{ expression }}.
For example, these are valid expressions in Angular:
1+2
a+b
user.name
items[index]](https://image.slidesharecdn.com/angularjs-abriefintroduction-151006132747-lva1-app6891/85/Angular-JS-A-Brief-Introduction-10-320.jpg)

- 1. A Brief Introduction Fernando Mano
- 2. What is AngularJS? Not (only) a library "AngularJS is a structural framework for dynamic web apps" (AngularJS' official website)
- 3. Philosophy "Angular is what HTML would have been, had it been designed for applications" (AngularJS' official website) "Angular is built around the belief that declarative code is better than imperative when it comes to building UIs and wiring software components together," (AngularJS' official website)

- 11. Key Concepts - Templating
- 12. Key Concepts - Services
- 13. Why AngularJS? Uses and extends HTML Declarative templating Easily testable Encourages the use of MVC/MVVM design pattern Reusable Single-page applications
- 14. When NOT to use AngularJS? Intensive or tricky DOM manipulations → poor performance - GUI editors and games
