关于javascript:给lodash的memoize-增加expire过期功能

需要场景：对同一时间发动的大量反复参数雷同的申请做缓存，然而在过了几秒钟之后就不须要缓存了，须要从新向服务器申请最新的数据

lodash.memoize办法会在整个页面的生命周期。须要减少一个超时性能

思路：相似于防抖函数，每次判断是否超过设置工夫，超过就清空缓存列表

const myMemoize = (fn, duration = 2000) => {  let t = new Date().getTime();  const memoized = _.memoize(fn, (...args) => JSON.stringify(args));  return (...args) => {    const curr = new Date().getTime();    if (curr - t > duration) {      memoized.cache = new _.memoize.Cache();      t = curr;    }    return memoized(...args);  };};

ts版

export const myMemoize = <T extends (...args: any[]) => Promise<any>, R = ReturnType<T>>(fn: T, duration = 2000) => {  let t = new Date().getTime()  const memoized = memoize(fn,(...args: Parameters<T>) => JSON.stringify(args))  return (...args: Parameters<T>) => {    const curr = new Date().getTime()    if(curr - t > duration) {      memoized.cache = new memoize.Cache      t = curr    }    return memoized(...args) as unknown as R  }}
