Vue.js

Vue.js is a wildly popular, fiercely agile, and massively respected framework that completely disrupted the industry by sitting perfectly between React and Angular. Created by an independent developer (Evan You, formerly at Google), Vue took the strict enterprise power of Angular, stripped away the terrifying complexity, and combined it with the lightning-fast Virtual DOM speed of React. The absolute core superpower of Vue is its "Progressive Adaptability and Intuitive Syntax." Unlike Angular, which requires you to rewrite your entire app, Vue is 'progressive'. A developer can drop a single script tag into an old legacy HTML page to add interactivity, or they can use Vue CLI to build a massive, complex Single Page Application. Its templating syntax (using standard HTML) is famously easy for designers and junior developers to learn. Because it offers an incredibly smooth learning curve, stunning performance, and massive popularity in the Asian market (heavily used by Alibaba and Tencent), it is the absolute darling of creative web agencies, agile startups, and massive open-source projects.
