随着 Angular, React, VUE 的流行，大家可能已经遗忘了老牌MVC框架 Backbone.js，自2016年4月 v1.3.3 版本后作者就没有任何更新了，时隔3年后 2019年2月19号作者进行了更新，发布了 1.4.0 ，呵呵。
1.4.0 — Feb. 19, 2019 — Diff — Docs
- Collections now support the Javascript Iterator Protocol!
- listenTo uses the listened object's public on method. This helps maintain interoperability between Backbone and other event libraries (including Node.js).
- Added support for setting instance properties before the constructor in ES2015 classeswith a preinitialize method.
- Collection.get now checks if obj is a Model to allow retrieving models with an `attributes` key.
- Fixed several issues with Router's URL hashing and parsing.
如果你的前端还需要支持 IE7+ 浏览器，那 Backbone.js 是你的首选：小巧、简单、强大。
