Added functions to get prediction from server given a message body

function getPrediction() {

    document.getElementById("prediction").innerText = "ham"

    var url = "http://localhost:8080"

    var endpoint = "/predict"

    var http = new XMLHttpRequest();

    http.open("GET", url + endpoint, true);

    http.onreadystatechange = function() {

        var DONE = 4;       // 4 means that the request is done

        var OK = 200;       // 200 means a successful return

        if (http.readyState == DONE && http.status == OK && http.responseText) {

            // JSON string

            replyString = http.responseText;

            // JSON -> JS obj

            replyObj = JSON.parse(replyString);

            document.getElementById("prediction").innerText = replyObj.prediction;  // signifies that we need a string called prediction from the backend

        }

    }

}

function getTopFiveAlgorithms() {

    var url = "http://localhost:8080"

    var endpoint = "/getAlgorithms"

    var http = new XMLHttpRequest();

    http.open("GET", url + endpoint, true);

    http.onreadystatechange = function () {

        var DONE = 4;       // 4 means that the request is done

        var OK = 200;       // 200 means a successful return

        if (http.readyState == DONE && http.status == OK && http.responseText) {

            // JSON string

            replyString = http.responseText;

            // JSON -> JS object

            replyObj = JSON.parse(replyString);

            // put the algorithm names in their ranked order

            // put the algorithms' F1 scores in their ranked order

        }

    }
