const processSaleBoundArr = async (saleBoundArr, tokenData, accountData) => { let saleOutBounds = [] if (saleBoundArr?.length > 0) { let customerIds = [], customArr = [] for (const item of saleBoundArr) { customerIds.push(item.customer_id) customerIds = Array.from(new Set(customerIds)); } for (const i of customerIds) { const customerDetailRes = await getCustomerDetail( { id: i }, { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain } ); if (customerDetailRes.data.errcode === 0) { const customerData = customerDetailRes.data.data customArr.push(customerData) } } for (const s of saleBoundArr) { for (const c of customArr) { if (s.customer_id === c.customer_id) { s.account_open_addr = c.account_open_addr s.addr = c.addr s.bank = c.bank s.bank_account = c.bank_account s.taxpayer_no = c.taxpayer_no s.orgName = c.sale_dept_name saleOutBounds.push(s) } } } } return saleOutBounds } 优化代码

以下是对上述代码的优化建议：

1. 对于 `saleBoundArr?.length > 0` 这个条件判断，可以使用 `if (saleBoundArr && saleBoundArr.length)` 来代替，更加简洁明了。

2. 在获取客户详细信息的过程中，可以使用 `Promise.all()` 方法并行获取多个客户的详细信息，避免顺序执行耗费时间。

3. 可以使用 `Array.prototype.find()` 方法代替双重循环查找客户详细信息，提高查找效率。

4. 在获取客户详细信息时，可以使用 `map()` 方法将客户 `id` 数组转换为客户详细信息数组，避免使用多次 `push()` 方法。

下面是优化后的代码示例：

const processSaleBoundArr = async (saleBoundArr, tokenData, accountData) => {
  let saleOutBounds = [];

  if (saleBoundArr && saleBoundArr.length) {
    const customerIds = [...new Set(saleBoundArr.map(item => item.customer_id))];
    const customerPromises = customerIds.map(id => {
      return getCustomerDetail(
        { id },
        { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain }
      );
    });
    const customerDetails = await Promise.all(customerPromises);

    saleOutBounds = saleBoundArr.map(saleBound => {
      const customerDetail = customerDetails.find(detail => detail.data.errcode === 0 && detail.data.data.customer_id === saleBound.customer_id);
      if (customerDetail) {
        const customerData = customerDetail.data.data;
        saleBound.account_open_addr = customerData.account_open_addr;
        saleBound.addr = customerData.addr;
        saleBound.bank = customerData.bank;
        saleBound.bank_account = customerData.bank_account;
        saleBound.taxpayer_no = customerData.taxpayer_no;
        saleBound.orgName = customerData.sale_dept_name;
      }
      return saleBound;
    });
  }

  return saleOutBounds;
};

这个优化后的代码使用了一些 JavaScript 的高级语法，如 `Promise.all()` 和 `Array.prototype.find()` 方法，使代码更加简洁高效。
