All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
Hi Nicholas,
I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:
The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
In some cases the IC might determine that a PM meeting for the incident isn't needed.
If the IC decides to waive the meeting please replace the Meeting section with a

First up, let's make Sublime Text 2 available from the command line in terminal, by creating a link to subl which is the launcher from terminal:
ln -s /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl /usr/local/bin/sublime
(added bonus of this approach is when you upgrade to ST3 or change text editor, you can just redirect the symlink).
If there's any chance that bash doesn't check usr/local/bin then use [Launch Sublime Text 2 from Mac OSX Terminal] for more detailed instructions on how to make this happen.

| // A short snippet for detecting versions of IE in JavaScript | |
| // without resorting to user-agent sniffing | |
| // ---------------------------------------------------------- | |
| // If you're not in IE (or IE version is less than 5) then: | |
| // ie === undefined | |
| // If you're in IE (>=5) then you can determine which version: | |
| // ie === 7; // IE7 | |
