推荐答案

localStorage 和 sessionStorage 都是所谓的 WebStorage 和特性HTML5.

localStorage and sessionStorage are both so-called WebStorages and features of HTML5.

localStorage 存储信息，只要用户不删除它们.

localStorage stores information as long as the user does not delete them.

sessionStorage 会在会话期间存储信息.通常直到用户关闭选项卡/浏览器.

sessionStorage stores information as long as the session goes. Usually until the user closes the tab/browser.

cookies 只是 cookie，受旧浏览器支持，通常是使用上述 WebStorages 的框架的后备.

cookies are simply cookies, which are supported by older browsers and usually are a fallback for frameworks that use the above mentioned WebStorages.

相比之下，cookie 可以存储的信息比 WebStorages 少得多，而且 WebStorages 中的信息永远不会传输到服务器.

In contrast cookies can store way less information then WebStorages and the information in WebStorages is never transferred to the server.

请记住，欧盟有一项法规要求网站通知其用户有关 Cookie 的使用情况.我不知道这是否也适用于 WebStorages

Keep in mind that the EU has a regulation that requires websites to inform their users about the usage of cookies. I dont know whether this also applies to WebStorages
