WeChat Mini Programs uses setdata to change the value of an attribute in an object array

/ / like
api.addLikeDiary (data). Then ((res) = > {

  if (res.code == 0) {
    let index = event.currentTarget.dataset.index  // 
    let isLike = this.data.diaryListInfo[`${index}`].isLike
    let likeCount = this.data.diaryListInfo[`${index}`].likeCount
    this.setData({
      [isLike]:!isLike
    })
    if (isLike) {
      this.setData({
        [likeCount]: likeCount -= 1
      })
    } else {
      this.setData({
        [likeCount]: likeCount += 1
      })
    }
  }
})

this.setData ({

)

  [isLike]:!isLike

}) cannot be reversed

this.setData({
      [isLike]:!isLike//isLike
    })

like this?

let isLike = "diaryListInfo[`${index}`].isLike"
let likeCount = "diaryListInfo[`${index}`].likeCount"

this.setData({
  [isLike]:!this.data.diaryListInfo[`${index}`].isLike
})
