javascript - 使用 for 循环为数组提供错误

Question

我使用以下代码按预期工作，同时使用 ESLINT
我有错误

ESLint: iterators/generators require regenerator-runtime, which is too heavyweight for this guide to allow them. Separately, loops should be avoided in favor of array iterations. (no-restricted-syntax)

这是代码

for (const subscription of resp.data.subscriptions) {
  if (subscription.url) {
    return subscription.url;
  }
}

代码很简单

从其他函数获取数据数组

在每个数组项上循环

当第一个数组实例有 url 并返回

有没有办法更好地编写它以避免 eslint 问题？

Answer 1

有一个关于for...of的争论用法here及其最终的限制

for(let i = 0; i < array.length; i ++) { ... } is antiquated syntax, and while I know everyone understands what it means, we should be leaving it behind.

array.map has functional connotations and we shouldn't be producing side effects in the closure.

array.forEach is an option, but I personally don't like it for this sort of imperative work.

So I think the ForOfStatement should be removed from the restricted syntax for the above reasons - anyone with any conflicting viewpoints? Do we know what the original justification is?

for..of比 forEach 贵, 检查 this出去
我没有意见，你可以删除 eslint 规则
