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>当命名构造函数或类名时,使用驼峰式写法// 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');
// bad
var CheckBox = require('./check_box');
// good
var CheckBox = require('./CheckBox');
