Angular Vs React.

Introduction

Angular is a TypeScript-based open-source web application framework led by the Angular Team at Google and by a community of individuals and corporations. Angular is a complete rewrite from the same team that built AngularJS.

React is an open-source, front end, JavaScript library for building user interfaces or UI components. It is maintained by Facebook and a community of individual developers and companies. React can be used as a base in the development of single-page or mobile applications.

Testing in Angular & React

Jest is used by Facebook to tests its React code. It is included in every React project and requires zero configuration to use. It also includes a powerful mocking library. Many times Jest is used in combination with Enzyme (a JavaScript testing utility used at Airbnb).

Jasmine is a testing framework that can be used in Angular. Eric Elliott says that Jasmine “results in millions of ways to write tests and assertions, needing to carefully read each one to understand what it’s doing”. The output, in my opinion, is also very bloated and difficult to read. Here are some educational articles on the integration of Angular with Karma and Mocha.

Conclusion

React is faster than angular but its complex structure is difficult to understand then angular’s. The main difference that put react ahead is the way of updating virtual DOM. React only changes the components by finding there ids and angular updates whole DOM when changes is made.
