// A common redux pattern when dealing with async functions is to use thunk.
// This usually means your action returns a new function instead of an action object,
// and the thunk middleware will make it all work. Example:
const asyncAction = () => dispatch => setTimeout(() => dispatch(someOtherAction()), 10000);

// Now: maybe that async stuff going on is calling some API which you don't want to overload
// with request, and that's what debounce is for.
// This is an example of a debounced function which will only be calleable once every second.
import { debounce } from 'lodash';
const debouncedFn = debounce(() => callApi(), 1000, { leading: true, trailing: false });

Fundamentals

Store any kind of data using the following graph concepts:

• Node: Graph data records
• Relationship: Connect nodes (has direction and a type)
• Property: Stores data in key-value pair in nodes and relationships
• Label: Groups nodes and relationships (optional)

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

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.
