About Vue.js iii “Mark my words: Vue.js will sky-rocket in popularity in 2016. It’s that good.” — Jeffrey Way “Vue is what I always wanted in a JavaScript framework. It’s a framework that scales with you as a developer. You can sprinkle it onto one page, or build an advanced single page application with Vuex and Vue Router. It’s truly the most polished JavaScript framework I’ve ever seen.” — Taylor Otwell “Vue.js is the first framework I’ve found that feels just as natural to use in a server-rendered app as it does in a full-blown SPA. Whether I just need a small widget on a single page or I’m building a complex Javascript client, it never feels like not enough or like overkill.” — Adam Wathan “Vue.js has been able to make a framework that is both simple to use and easy to understand. It’s a breath of fresh air in a world where others are fighting to see who can make the most complex framework.” — Eric Barnes “The reason I like Vue.js is because I’m a hybrid designer/developer. I’ve looked at React, Angular and a few others but the learning curve and terminology has always put me off. Vue.js is the first JS framework I understand. Also, not only is it easy to pick up for the less confidence JS’ers, such as myself, but I’ve noticed experienced Angular and React developers take note, and liking, Vue.js. This is pretty unprecedented in JS world and it’s that reason I started London Vue.js Meetup.” —Jack Barham
About Vue.js iv Comparison with Other Frameworks Angular There are a few reasons to use Vue over Angular, although they might not apply for everyone: • Vue.js is much simpler than Angular, both in terms of API and design. You can learn almost everything about it really fast and get productive. • Vue.js is a more flexible, less opinionated solution. That allows you to structure your app the way you want it to be, instead of being forced to do everything the Angular way. It’s only an interface layer so you can use it as a light feature in pages instead of a full blown SPA. It gives you bigger room to mix and match with other libraries, but you are also responsible for making more architectural decisions. For example, Vue.js’ core doesn’t come with routing or ajax functionalities by default, and usually assumes you are building the application using an external module bundler. This is probably the most important distinction. • Angular uses two-way binding between scopes. While Vue also supports explicit two-way bindings, it defaults to a one-way, parent-to-child data flow between components. Using oneway binding makes the flow of data easier to reason about in large apps. • Vue.js has a clearer separation between directives and components. Directives are meant to encapsulate DOM manipulations only, while Components stand for a self-contained unit that has its own view and data logic. In Angular there’s a lot of confusion between the two. • Vue.js has better performance and is much, much easier to optimize, because it doesn’t use dirty checking. Angular gets slow when there are a lot of watchers, because every time anything in the scope changes, all these watchers need to be re-evaluated again. Also, the digest cycle may have to run multiple times to “stabilize” if some watcher triggers another update. Angular users often have to resort to esoteric techniques to get around the digest cycle, and in some situations there’s simply no way to optimize a scope with a large amount of watchers. Vue.js doesn’t suffer from this at all because it uses a transparent dependencytracking observing system with async queueing - all changes trigger independently unless they have explicit dependency relationships. The only optimization hint you’ll ever need is the track-by param on v-for lists. Interestingly, there are quite some similarities in how Angular 2 and Vue are addressing these Angular 1 issues.
