/**
 * 返回一个对象，对象由给定对象中通过`predicate`真值检测的元素组成。
 *
 * @example
 * pick({ name: 'moe', age: 50, userid: 'moe1' }, 'age')
 * => { age: 50 }
 *
 * pick({ name: 'moe', age: 50, userid: 'moe1' }, ['name', 'age'])
 * => { name: 'moe', age: 50 }
 *
 * pick({ name: 'moe', age: 50, userid: 'moe1' }, function(value, key, object) {
 *   return isNumber(value)
 * })
 * => { age: 50 }
 *
 * @param object 给定对象
 * @param predicate 谓语迭代器函数，通过 iteratee 进行转换，以简化速记语法
 * @param context 上下文对象，若传递，则作为谓语迭代器函数的执行上下文 this
