{ "linter": { "rules": { "complexity": { "useDateNow": "error" } } }}¥Description
使用 Date.now() 获取自 Unix 纪元以来的毫秒数。
¥Use Date.now() to get the number of milliseconds since the Unix Epoch.
Date.now() 比 new Date().getTime() 及其变体更具可读性，它还避免了不必要的 Date 对象实例化。
¥Date.now() is more readable than new Date().getTime() and its variants,
it also avoids unnecessary instantiation of Date object.
