“What if we had a robust and complete front-end solution for making high-performance and supremely scalable applications?”. That is probably what developers at Google thought when they devised AngularJS. Nearly a decade (and a complete rewrite in 2016) later, Angular sits atop of frontend frameworks. Why is that?
Angular flawlessly solves the widest variety of software development problems that center around building apps. While web apps remain its main focus, it may just as well be used to build mobile web and native apps, or even desktop software. While other solutions need to be combined with various tools to capture all aspects of the modern app development, Angular does most of the job by itself.
