Article Introduction：Core points Angular 2.0 uses TypeScript (a superset of JavaScript) to optimize performance, improve page speed and workflow automation. TypeScript allows developers to use type information to annotate JavaScript code, thus helping to catch errors in the code base. Angular 2.0 introduces the concept of components, which are reusable blocks of code that contain views and logic. Components replace instructions as the main element of the framework, ensuring that one part of the application's code does not interfere with another part of the code.

Article Introduction：The SPA can change content without refreshing the page because it uses JavaScript to dynamically update the local content of the page, and implements it with the help of front-end framework and asynchronous loading technology. Its core mechanisms include: ① Request data from the server through AJAX or FetchAPI; ② Use front-end routes to manage URL changes; ③ Replace part of the content instead of full page overloading in existing pages. This mode is suitable for scenes such as backend management systems, social network interfaces, online editing tools, etc. that require frequent interaction, but attention should be paid to SEO optimization, home screen loading speed, memory management and browser compatibility. During development, it is recommended to use code chunking, evaluate whether SSR or static generation is introduced, and continuously monitor performance to ensure user experience and application stability.
