What forces layout / reflow

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.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

• Close Android File Transfer
• Open Activity Monitor and kill “Android File Transfer Agent”
• Go to where you installed “Android File Transfer.app” (I have it under /Applications)
• Ctrl+click –> “Show package contents”
• Go to Contents/Resources
• Rename “Android File Transfer Agent” to e.g. “Android File Transfer Agent_DISABLED”
• Then go to “/Users/username/Library/Application Support/Google/Android File Transfer” and again rename the Agent app.

This is no longer needed as Emmet supports JSX - you just need to turn it all on. Did a quick tutorial: http://wesbos.com/emmet-react-jsx-sublime/

Thanks, @wesbos

Problem

• Using emmet in jsx files
• Emmet expands text when js autocomplete needed

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

Due to the high usage of this guide and the lack of comfort in Gist's commenting area, I decided to make a blog post out of this which you can find here:
