Same as my other like gist but without using jQuery

Like (without jQuery).js

import axios from "axios"

var failedAttemptCount = 0

class Like {
  constructor() {
    if (document.querySelector(".like-box")) {
      axios.defaults.headers.common["X-WP-Nonce"] = universityData.nonce
      this.events()
    }
  }

  events() {
    document.querySelector(".like-box").addEventListener("click", e => this.ourClickDispatcher(e))
  }

  // methods
  ourClickDispatcher(e) {
    let currentLikeBox = e.target
    while (!currentLikeBox.classList.contains("like-box")) {
      currentLikeBox = currentLikeBox.parentElement
    }

    if (currentLikeBox.getAttribute("data-exists") == "yes") {
      this.deleteLike(currentLikeBox)
    } else {
      this.createLike(currentLikeBox)
    }
  }

  async createLike(currentLikeBox) {
    try {
      const response = await axios.post(universityData.root_url + "/wp-json/university/v1/manageLike", { "professorId": currentLikeBox.getAttribute("data-professor") })
      if (response.data != "Only logged in users can create a like.") {
        currentLikeBox.setAttribute("data-exists", "yes")
        var likeCount = parseInt(currentLikeBox.querySelector(".like-count").innerHTML, 10)
        likeCount++
        currentLikeBox.querySelector(".like-count").innerHTML = likeCount
        currentLikeBox.setAttribute("data-like", response.data)
      }
      console.log(response.data)
    } catch (e) {
        alert("Oops something went wrong :( \nAre you logged in?")
        console.log(response)
        failedAttemptCount++
        console.log(failedAttemptCount)
        if (failedAttemptCount >= 2) {

  }
}

export default Like
