React vs AngularJS — React Technical Interview Questions & Answers

React vs AngularJS

React vs AngularJS

  • AngularJS is Angular 1: two-way ng-model, digest cycle, controllers. React is a UI library with one-way data. Do not say AngularJS when you mean Angular 2+ (TypeScript, components, DI). Interviewers listen for that naming fix.
  • React vs AngularJS — output: two-way vs one-way + naming trap. Freshers mix AngularJS and Angular.

Technical Interview Tip: Name the 1.x vs 2+ trap.
