Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Vectors and Sequences

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

In Terminal

mkdir ~/.bash

Copy the raw git-prompt.sh file from git contrib in to the ~/.bash directory: https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh

Inside ~/.bashrc or ~/.bash_profile (choose the file where you normally put any bash customizations/setup), add the lines:

	open System
	open System.ServiceModel
	open System.ServiceModel.Description

	[<ServiceContract(ConfigurationName = "PublishService", Namespace = "http://xyz.gov/PublishService")>]
	[<ServiceBehavior(InstanceContextMode=InstanceContextMode.PerSession)>]
	type IPublishService =

	abstract member TestMethod : name:string -> string

	namespace MyNamespace

	type IMyInterface =
	abstract GetValue: unit -> string

	type MyRecord =
	{ MyField1: int
	MyField2: string }
	interface IMyInterface with
	member x.GetValue() = x.MyField2
