chatGPT教我写compose函数的详细过程

mounted() {
    // 定义一个通用的 compose 函数
    // 这个可以提取到公共函数去
    const compose = (...fns) => {
      return fns.reduceRight((prevFn, nextFn) => {
        return async (...args) => {
          return nextFn(await prevFn(...args));
        };
      });
    };

    const asyncFunc1 = () => {
      return new Promise(resolve => {
        setTimeout(() => {
          console.log('Async Function 1');
          resolve(100);
        }, 1000);
      });
    };

    const asyncFunc2 = num => {
      return new Promise(resolve => {
        setTimeout(() => {
          console.log('Async Function 2');
          resolve(num + 50);
        }, 500);
      });
    };

    const syncFunc = num => {
      console.log(num)
      console.log('Sync Function');
      return num + 10;
    };

    const syncFunc2 = num => {
      console.log(num)
      console.log('Sync Function 2');
      return num + 10;
    };

    const runAllAsyncFunctions = compose(asyncFunc2, syncFunc2, asyncFunc1, syncFunc);

    const run = async () => {
      const result = await runAllAsyncFunctions();
      console.log('All functions completed');
      console.log('Result:', result);
    };

    run();

  }
