This is a way to have the fictional univeristy website redirect you to the register page with too many failed attempt to like a professor

Like (with jQuery).js

import $ from 'jquery';

var failedAttemptCount = 0

class Like {
    constructor() {
        this.events();
    }

    events() {
        $(".like-box").on("click", this.ourClickDispatcher.bind(this))
    }

    // Methods
    ourClickDispatcher(e) {
        var currentLikeBox = $(e.target).closest(".like-box")

        if(currentLikeBox.data('exists') == "yes") {
            this.deleteLike(currentLikeBox)
        } else{
            this.createLike(currentLikeBox)
        }
    }
        
    createLike(currentLikeBox) {
        $.ajax({
            beforeSend: (xhr) => {
                xhr.setRequestHeader('X-WP-Nonce', universityData.nonce);
            },
            url: universityData.root_url + '/wp-json/university/v1/manageLike',
            type: 'POST',
            data: {'professorId': currentLikeBox.data('professor')},
            success: (response) => {
                console.log(response);
            },
            error: (response) => {
                alert("Oops something went wrong :( \nAre you logged in?")
                console.log(response)
                failedAttemptCount++1;
                console.log(failedAttemptCount)
                if (failedAttemptCount >= 2) {
                    window.location.href = universityData.root_url + '/wp-login.php?action=register';
                }
            }
        })
    }

    deleteLike() {
        $.ajax({
            url: universityData.root_url + '/wp-json/university/v1/manageLike',
            type: 'DELETE',
            success: (response) => {
                console.log(response);
            },
            error: (response) => {
                console.log(response)
            }
        })
    }
}

export default Like;
