JavaScript Etiquette

Javascript Pragma

These practices revolves around the pragmatic approach to JavaScript coding which deals with practical usage rather than theoretical considerations.

The "use strict" pragma?

"use strict" is a language construct that tells the compiler how to interpret the document. If you are familiar with html doctype or character encoding, they serve similar purposes.

General Considerations

it works
it's easy to understand
it should be easy to do

Namespacing

Use long, descriptive variable and method names

var bindAllButtons = function() { /**/ },
	redirectURL = 'http://www.isobarhub.com',
	redirectButtonClass = '.button--redirect';

Encapsulation

Encapsulation includes the idea that the data of an object should not be directly exposed. Instead, callers that want to achieve a given result are coaxed into proper usage by invoking methods (rather than accessing the data directly).

var person = {
	"fullName": "Jubal Mabaquiao"
}

alert(person.fullName); // Jubal Mabaquiao
person.fullName = "Juan Dela Cruz"
alert(person.fullName); // Juan Dela Cruz
