return func(collection, getIteratee(iteratee, 3)); } 为了简化问题,我们分析比较简单的情况:用一个func函数处理数组。 _.map([1,2,3],func); 在处理数组的时候,lodash是分开处理的,对于Array采用arrayMap进行处理,对于对象则采用baseMap进行处理。

Util的_.noConflict()方法用于将变量恢复为以前的值,并返回对lodash函数的引用。 用法: _.noConflict() 参数:此方法不接受任何参数。 返回值:此方法返回lodash函数。 例: Javascript // Requiring lodash libraryconst_ =require('lodash');// Calling _.noConflict() methodvarlod = _.noConflict();// Disp...
