在最简单的是，也许这：
const time = "125657".replace(/(..?)(..)(..)/, "$1:$2:$3");
const date = "20190702".replace(/(....)(..)(..)/, "$2/$3/$1");
console.log(date, time);如果时间字符串可以是5位而不是6位，则可以使用第一种模式中的问号。如果您确定总是得到6位，则可以将其省略。

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
