如何处理 Unexpected use of逗号运算符 no-sequences EsLINT 警告 [英] How to deal with Unexpected use of comma operator no-sequences EsLINT warning

问题描述

由于意外使用逗号，我收到 eslint 警告.我找到了这个答案，但它与我的问题不符.>

我有这个代码

const 减少 = _.map(_.keys(grouped), function(e) {return _.reduce(grouped[e], function(r, o) {返回 r.count += +o.amount, r}, {price: parseFloat(e), count: 0, amount: e.amount})})

如何解除警告?非常感谢.

解决方案

你在.reduce回调中的return语句可以写成

 r.count += +o.amount;返回 r;

这完全相同，但它应该让 ESLint 高兴.

I am getting an eslint warning for unexpected use of comma. I found this answer but it does not match my issue.

I have this code

const reduced = _.map(_.keys(grouped), function(e) {
        return _.reduce(grouped[e], function(r, o) {
          return r.count += +o.amount, r
        }, {price: parseFloat(e), count: 0, amount: e.amount})
      })

How do I get rid of the warning? Thank you very much.

解决方案

Your return statement in the .reduce callback can be written as

  r.count += +o.amount;
  return r;

That does exactly the same thing, but it should make ESLint happy.
