【问题描述】：
我有以下功能：
const sort = (query) => (choiceA, choiceB) => choiceA.name.toLowerCase().localeCompare(choiceB.name.toLowerCase()),
用法如下：
newSearches = newSearches.sort(sort(query));
例如，在这个例子中，tarascon 应该是第一个结果，等等...
const query = 't';

【问题讨论】：
-
请在您的代码中为
newSearches分享一些数据，并分享您的预期输出应该是什么样子以及排序后现在的样子。 -
什么是
query？有排序的方向吗？ -
@adiga，标题中写着query是一个字符串。由于
query是一个字符串，例如，如果我查询p，我希望首先使用Paris，而不是Saint-Tropes。 -
我添加了一个例子
-
如果
query="p"，在搜索结果中Maussane-les-Alpilles应该高于Paris还是低于Paris？该名称包括P，但它不以p开头。您想检查name是否以query开头，还是只想检查它是否包含在name中？
