Web development, like most technologies, moves in waves and cycles. Static websites were all we had in the beginning. But, pretty soon, developers were hacking together the first server-generated sites thanks to Perl and PHP. This was the advance that would eventually kickstart frameworks like Laravel, Django, or Rails.
Mobile devices would come to change how people consume the web. So long server-generated websites, hello client-rendered applications. The next wave brought frameworks that could give users a more app-like experience—without reloads—like React or AngularJS.
