今天再使用airbnb的eslint写react的时候有一个很意外的报错,Do not use Array index in keys,不允许用index来作为列表的key,情况类似以下代码data.map((item, index) => { return( {item} ); })因为不管是react还是vue通常这种列表的渲染,如果本身没有id的话我都会把key传成index,而且react官方文档中也有一...

使用效果:useEffect是按照顺序执行代码的,改变屏幕像素之后执行(先渲染,后改变DOM),当改变屏幕内容时可能会产生闪烁;useLayoutEffect是改变屏幕像素之前就执行了(会推迟页面显示的事件,先改变DOM后渲染),不会产生闪烁。useLayoutEffect总是比useEffect先执行。 在未来的趋势上,两个 API 是会长期共存的,暂时没有删减合并...

Sentry SDK 将任何上下文数据标准化到给定的深度。任何包含结构比这更深的数据的 key 都将使用其类型([Object] 或 [Array])进行修剪和标记,而不会进一步遍历树。默认情况下,步行执行 3 级深度。 集成配置 对于许多平台,SDK 集成可以与之一起配置。在一些平台上,这是 init() 调用的一部分,而在另一些平台上,...
