javascript - 删除箭头函数的 javascript 警告

Question

我有这个功能

const currentClaims = claimOpenList.filter(c => {

  if (`${c.claimid}` === claimid || (claimid !== undefined && c.claimid_ === claimid)) {
    console.log('claimOpenList > Se encontro claimid: ', claimid)
    return c
  }else {null}
})

它可以工作并完成它应该做的事情，但我想摆脱这个警告:

Expected to return a value at the end of arrow function array-callback-return

它说问题就在眼前

  const currentClaims = claimOpenList.filter(c => {

Answer 1

您应该在方法中返回如下所示的内容

const currentClaims = claimOpenList.filter(c => {

  if (`${c.claimid}` === claimid || (claimid !== undefined && c.claimid_ === claimid)) {
    console.log('claimOpenList > Se encontro claimid: ', claimid)
    return c
  }
  return false;
})
