vue实现一个队列自动机

Posted 2022-12-05 小章鱼哥

最近比较忙，有时间完善思路。

关键代码

export function promiseQueue(executors: any[]) 
  return new Promise((resolve, reject) => 
    if (!Array.isArray(executors))  executors = Array.from(executors); 
    if (executors.length <= 0)  return resolve([]); 

    const res: any[] = [];
    executors = executors.map((x, i) => () => 
      const p = typeof x === 'function' ? new Promise(x) : Promise.resolve(x);
      p.then(response => 
        res[i] = response;
        if (i === executors.length - 1) 
          resolve(res);
         else 
          executors[i + 1]();
        
      , reject);
    );
    executors[0]();
  );
