Where art thou-freecodecamp算法题目 Where art thou 1.要求 写一个 function,它遍历一个对象数组(第一个参数)并返回一个包含相匹配的属性-值对(第二个参数)的所有对象的数组。 如果返回的数组中包含 source 对象的属性-值对,那么此对象的每一个属性-值对都必须存在于 collection 的对象中。 2.思路 用Objec...
Where do I belong (freeCodeCamp) 先给数组排序,然后找到指定的值在数组的位置,最后返回位置对应的索引。 举例:where([1,2,3,4], 1.5)应该返回1。因为1.5插入到数组[1,2,3,4]后变成[1,1.5,2,3,4],而1.5对应的索引值就是1。 同理,where([20,3,5], 19)应该返回2。因为数组会先排序为[3,5,2...
