为什么在for ... of循环中收到"no-unused-vars"警告，我该如何解决? [英] Why am I getting a 'no-unused-vars' warning in a for...of loop and how do I fix it?

问题描述

我正在使用Create React App创建的React应用程序.在每个for ... of循环中，我得到这个奇怪的'no-unused-vars'警告，指向我在for语句中实例化的变量.

I'm working on a React app created with Create React App. In every for...of loop, I get this weird 'no-unused-vars' warning pointing to the variable I have instantiated in the for statement.

ESLint告诉我我的变量未使用，但实际上已使用.

其他人也会收到类似的警告吗?是ESLint错误还是我在这里做错了什么?
这不是什么大问题，但是很烦人.
感谢您的帮助.

Does anybody else get a similar warning? Is it an ESLint bug or am I doing something wrong here?
This is not a big issue, but it is annoying.
Thanks for your help.

   for (let track of tracks) {
        let chords = RavelFormatter.splitEntries(track.pitches)
        for (let chord of chords) {
            var n = chord.split(':')
            total += n.length
        }
    }

控制台输出

  Line 13:  'track' is defined but never used       no-unused-vars
  Line 15:  'chord' is defined but never used       no-unused-vars
