Automatically cast some common datatypes in JavaScript

castit

Opinionated Javascript variable casting with deep structures support for easily and automatically cast some common datatypes in JavaScript

Based on https://github.com/bahamas10/node-autocast but adapted for Fluid Configure existing JSON configurations. This version is meant to be used in CommonJS environments.

The main differences with autocast are:

• hexadecimal and octals are not automatically casted, they remain as string values. Casing them is as simple as adding a plus sign in front of the string +"0xff".
• "" and "-" are both casted to an empty string.
• functions objects and array are not casted by default
• supports deep casting by passing an optional deep flag.
