The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

捕捉浏览器中的JS运行时错误，主要通过监听window.onerror来实现。但是对于不同的脚本执行方式以及不同的浏览器，能捕获到的信息会有区别。

window.onerror 讲接收3个参数：

• msg：错误描述，比如：a is not defined
• url：出错脚本所在的url
• lineNumber：出错脚本的行数

本文将对不同浏览器和不同的脚本执行方式进行测试，并总结这些区别。
