Difference Between ReactJS and Angular 4
What is React JS?
What is Angular 4?
Angular 4 has backward compatibility with Angular 2. That means the project developed in Angular 2 will work without any issues in Angular 4. An angular community has introduced some significant improvement to Angular 4, and thus, the major version number has been changed from 2 to 4, skipping 3. The reason behind that direct jump to version 4 was that the router package was in version 3.x, so instead of putting everything to 3.0 and the router to 4.0, the team chose to upgrade the versions of all the ng – modules to 4.0. There are major changes that have been introduced in Angular 4. TypeScript 2.1 and 2.2 have brought nice features; a new SystemJS plugin has been added, which dynamically converts component-relative path in TemplateURL and StyleURLs to absolute paths for a developer. Angular compiles the templates during the build, generate the JS code; in Just in Time mode, a compilation is done at runtime. Ahead of Time compilation has several advantages, at build time, template correctness is known instead of having to wait till runtime. Also, in Angular 4, segregated animation package from the core as a separate and dedication package. The template tag is now deprecated. Although it still works, one can use an ng-template tag. Angular 4 applications are smaller and faster when compared to Angular 2.

Below is the top 8 difference between ReactJS vs Angular 4
Key Difference between ReactJS and Angular 4
Below is the list of points describing the difference between ReactJS vs Angular 4
- ReactJS is best utilized for dynamic and single page applications since it uses virtual DOM, can quickly react to data changes, whereas Angular 4 is best suited for creating cross-platform mobile apps and progressive enterprise web applications and software.
- ReactJS uses one-way data binding means any model changes can affect the view, but not vice-versa, whereas Angular 4 uses two-way data binding means any model changes would affect the view and vice versa.
- ReactJS uses virtual DOM, which is a simplified version of DOM, whereas Angular 4 uses a browser’s DOM.
- ReactJS is better in-term of performance for a single page application since virtual DOM render the page quickly, whereas Angular 4 uses a traditional browser’s DOM, making its performance a bit lethargic as compare to ReactJS.
- ReactJS has decent community support behind it, whereas Angular 4 has a strong community support system since it is more utilised than ReactJS.
- ReactJS is completely backwards compatible with previous versions, whereas Angular 4 is also backwards compatible with Angular 2 and beyond, but versions below Angular 2 are not backwards compatible.
