Observe the various types of variable memory footprint by heapdump(通过heapdump直观观察JS变量内存占用情况)

/*
* 使用heapdump这个工具,可以在Nodejs中做各种「内存探索实验」

Created November 13, 2013 04:22 — forked from jookyboi/javascript_resources.md
Here are a set of libraries, plugins and guides which may be useful to your Javascript coding.

Libraries

  • jQuery - The de-facto library for the modern age. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers.
  • Backbone - Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.
  • AngularJS - Conventions based MVC framework for HTML5 apps.
  • Underscore - Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects.
  • lawnchair - Key/value store adapter for indexdb, localStorage
