常用Lodash函数库的函数

项目中常用的

• _.isEmpty(value)

  _.isEmpty(null);
  // => true
   
  _.isEmpty(true);
  // => true
   
  _.isEmpty(1);
  // => true
   
  _.isEmpty([1, 2, 3]);
  // => false
   
  _.isEmpty({ 'a': 1 });
  // => false

• _.isEqual(value, other) 深层的比较

  var object = { 'a': 1 };
  var other = { 'a': 1 };
   
  _.isEqual(object, other);
  // => true
   
  object === other;
  // => false

• bind 通常在react中绑定this实例

• 做为装饰器，使用方法@Bind()

  function greet(greeting, punctuation) {
    return greeting + ' ' + this.user + punctuation;
  }
   
  var object = { 'user': 'fred' };
   
  var bound = _.bind(greet, object, 'hi');
  bound('!');
  // => 'hi fred!'
   
  // Bound with placeholders.
  var bound = _.bind(greet, object, _, '!');
  bound('hi');
  // => 'hi fred!'

• cloneDeep 深克隆
