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 tooheavyweight for this guide to allow them. Separately, loops should beavoided 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 beleaving it behind.

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

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

So I think the ForOfStatement should be removed from the restrictedsyntax 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
