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

Sorry, I have to disagree with the entire premise here.
A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.
Mastery comes from a combination of at least several of the following:
setProps - depends on reading the last reconciled props from the current reconciled state of the app, at the time of the call. It also depends on an object that doesn't necessarily need to be there outside reconciliation. This is unlike setState, which is state that needs to be there. setState is queued up and merged at the time of reconciliation. Not at the time of the call. setState has a side-effect but is not a stateful nor mutative API.
isMounted - reads the current state of the tree, which may be stale if you're in a batch or reconciliation.
getDOMNode/findDOMNode - Reads the currently flushed node. This currently relies on the state of the system and that everything has flushed at this time. We could potentially do a forced render but that would still rely on the state of the system allowing us to synchronously being able to force a rerender of the system. Note: in 0.14, refs directly to DOM node will resolve to the DOM node. This allow you to get access to a node at the time of its choos
These use separate document structures instead of HTML, some are more modular libraries than full editors

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.
open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl
You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html
