打破 lambda 表达式箭头的 TsLint 规则名称是什么？

Question

我使用了这样带有断箭头的语法。

const result = data.map( _ 
  => this.reallyLongExpressionSoBreakingArrowMakesSense(_));

然后我注意到 TsLint 标记了该地点并给了我以下信息。

Line terminator not permitted before arrow. (ts1200)

我在我的 tslint.json 中没有找到类似的东西，所以我去 the docs 看看实际名称是什么。据我所知，没有任何对应的消息。

消息对应的TsLint规则是什么？
消息后括号中的ts1200有什么意义？

Answer 1

As contributors said，此行为未修复：

I think it's unlikely anyone is using this syntax, since it's much harder to read, but if it breaks apps then it might not be worth fixing.

In addition:

However, the problem I ran into when I tried to fix this was that it's a real pain to work on the token-level in the checker. So I wonder if the benefit of the idea is actually worth the cost.

更新：

尽量让它们_ =>在同一行，但是在下一行调用你的方法：

const result = data.map( _ => 
    this.reallyLongExpressionSoBreakingArrowMakesSense(_));

Answer 2

似乎没有 tslint 规则，只有 ESLint。
ts1200 错误代码。检查一下 here. Check the original pr here.

我通过将粗箭头和表达式推到一行来解决这个问题
