// JSHint Configuration, Node.js Edition

|

// Julien Fontanet JSHint configuration
|
||||
//
|
||||
// This is an options template for [JSHint][1], forked from
|
||||
// haschek's [JSHint template][2]:
|
||||
// Changes from defaults:
|
||||
// - all enforcing options (except `++` & `--`) enabled
|
||||
// - single quotes
|
||||
// - indentation set to 2 instead of 4
|
||||
// - almost all relaxing options disabled
|
||||
// - allow expression statements (necessary for chai.expect())
|
||||
// - allow global strict (most of my devs are in Node.js or Browserify)
|
||||
// - environments are set to Browserify, mocha & Node.js
|
||||
//
|
||||
// * the environment has been changed to `node`;
|
||||
// * recent options were added;
|
||||
// * coding style has been adapted to node (e.g. 2 spaces
|
||||
// indenting, global use strict).

// == Enforcing Options ===============================================

//
|

// These options tell JSHint to be more strict towards your code. Use

||||
// useful when your codebase is shared with a big number of developers
|
||||
// with different skill levels.
