避免单字母名称，让名称具有描述性

// bad
function q() {
// ...stuff...
}


// good
function query() {
// ..stuff..
}

// bad
var OBJEcttsssss = {};
var this_is_my_object = {};
function c() {}
var u = new user({
name: 'Bob Parr'
});


// good
var thisIsMyObject = {};
function thisIsMyFunction() {}
var user = new User({
name: 'Bob Parr'
});<strong>
</strong>

// bad
function user(options) {
this.name = options.name;
}


var bad = new user({
name: 'nope'
});


// good
function User(options) {
this.name = options.name;
}


var good = new User({
name: 'yup'
});

// bad
this.__firstName__ = 'Panda';
this.firstName_ = 'Panda';


// good
this._firstName = 'Panda';

// bad
function() {
var self = this;
return function() {
console.log(self);
};
}


// bad
function() {
var that = this;
return function() {
console.log(that);
};
}


// good
function() {
var _this = this;
return function() {
console.log(_this);
};
}

// bad
var log = function(msg) {
console.log(msg);
};


// good
var log = function log(msg) {
console.log(msg);
};

// file contents
class CheckBox {
// ...
}
module.exports = CheckBox;


// in some other file
// bad
var CheckBox = require('./checkBox');
