Angular (commonly referred to as "Angular 2+" or "Angular CLI")[4][5]
is a TypeScript-based free and 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.
Angular is used as the frontend of the MEAN stack, consisting of MongoDB
database, Express.js web application server framework,
Angular itself (or AngularJS), and Node.js server runtime environment.
