AngularJS Vs ReactJS: Which Is The Best Front End Development Framework ?

AngularJS and ReactJS are two highly sought-after web frameworks in 2021, according to Statista. But choosing between them depends on your future needs. Initially, comparing Angular vs. React seems odd, as Angular is a framework and React is a library. However, both are used for interactive apps. Both are effective, though their approaches differ.

Recent years brought a shift in web app programming. Complex pages once needed full programs (like PHP/Apache or Java/JS/Tomcat). Current JS frameworks allow front ends to work with any language or system. Angular and React have become industry standards for front-end development. To determine the better choice, understand their differences and advantages.

Comparison: ReactJS vs. AngularJS                                                                                                                                                                     

AngularJS:

Built by Google, Angular JS is an open-source front-end framework on HTML/JS. It follows an MVC approach and is supported by a growing community. Angular is used for constructing dynamic web apps. It abstracts code for easier site creation.

Angular is a model-view-controller (MVC) platform that prescribes app structure. This boosts app speed but can limit flexibility. It's suitable for single-page (SPAs) and multi-page apps (MPAs) and includes the Ionic framework for mobile apps.

ReactJS:

ReactJS, by Facebook, aids UI creation. It's excellent for making interactive UI components quickly. It's used to build web pages and apps and is backed by a developer community. React's virtual DOM enhances loading times. It's ideal for high-quality user interfaces with less code.

Pros and Cons of Angular: Pros:

1. Supports MVC architecture
2. Rich built-in features
3. Good upkeep
4. High-performing web apps
5. Quick project setup using Angular-CLI                                                                                      
6. Simplifies app construction                                                                                                              
7. Easy unit and end-to-end testing

Cons:

1.Reloads whole HTML structure

2.Ionic app slows loading

3.Relatively rigid and inflexible

4.Requires training

5.Limited support for disabled JavaScript or obsolete browsers

Pros and Cons of React:

Pros:

• Fast data loading (Virtual DOM)
• Expected longevity
• Combines markup and logic
• Data-display separation
• Easy for beginners
• Simple library with few presets
• Smooth program execution

Cons:

• Limited to a library
• No MVC architecture
• Often requires additional libraries
• Best for highly interactive apps
• JSX mastery needed

Angular vs. React: Differences

• Angular is a comprehensive framework; React is a library.
• Angular uses TypeScript; React uses JSX.
• Angular suits large, multipurpose apps; React is for lightweight apps.
• Angular offers MVC architecture; React doesn't.
• Angular requires more learning; React is simpler.
• Angular reloads whole HTML; React uses Virtual DOM.
• Angular uses Ionic for mobile; React has React Native.

In conclusion, Angular is a comprehensive solution for large apps, while React is more flexible and suited for lightweight or UI-centric apps. Choose based on your needs, experience, and preferences.
