problem using .split() method in a function but it works on console.log

the problem is only in the bottom function objectPutter
specifically the line with wowza.split(' '); labelled with the comment
let eq
let x = null
let bracketNum = 0
let k = 0
let pre = 0
class subEqCreator { //subEq object
constructor() {
this.precede = 0;
this.text = '';
}
parser() {
this.text += eq[k]
}
ma() {
this.text.split(' ')
}
};
function trigger() { //used for HTML onClick method
show();
brackets();
subEqDynamic()
parseEquation();
objectPutter()
};
function show() {
const recent = document.querySelector("ol");
const txt = document.getElementById('input');
eq = txt.value;
li = document.createElement('li');
li.innerText = eq;
recent.appendChild(li);
txt.value = '';
};
function brackets() { //counts how many brackets appear
for (let i = 0; i < eq.length; i++) {
if (eq[i] == "(") {
bracketNum++;
};
};
};
let subEqDynamic = function() { // creates a new object for each bracket
for (let count = 0; count <= bracketNum; count++) {
this['subEq' + count] = x = new subEqCreator()
};
};
function parseEquation() { // assign characters to SubEq object
let nextIndex = 0;
let currentIndex = 0;
let lastIndex = [0];
let eqLen = eq.length;
let nex = this['subEq' + nextIndex]
for (k; k < eqLen; k++) {
if (eq[k] == "(") {
nextIndex++;
pre++
this['subEq' + currentIndex].text += '( )';
this['subEq' + nextIndex].precede = pre;
lastIndex.push(currentIndex);
currentIndex = nextIndex;
} else if (eq[k] == ")") {
pre--
currentIndex = lastIndex.pop();
} else {
this['subEq' + currentIndex].parser()
}
}
}
function objectPutter() {
for (let i = 0; i < bracketNum; i++) {
let wowza = this['subEq' + i].text
wowza.split(' '); // 🚩 why isnt it working here
console.log(subEq0);
for (let j = 1; j <= wowza.length; j += 2) { // for loop generates only odds
let ni = i++
wowza.splice(j, 0, this['subEq' + ni])
console.log(i)
}
}
}
to fix this i tried;
making a method for it ma() in the constructor.
putting in the function parseEquation above in case it was a scope issue.
also, i noticed subEq0.split(' ') worked in browser console even replicating it to the way i done it using this['subEq' + i].text.split(' ') where i = 0.
After it runs the it says .splice is not a function and console.log(subEq0) shows subEq0.text is still a string

.split() does not change the variable it returns the splitted variable

How to detect joy-con input/motion controls in HTML5 JavaScript

I am trying to create an HTML5 JavaScript game that uses Nintendo Switch Joy-Cons and motion controls. The problem is, I don't know how to detect motion controls from Joy-Cons when they are connected to my PC.
I've managed to achieve button inputs with Xbox controllers, PS4, and Joy Con using Gamepad API, but is it possible to do so with Joy-Con motion controls?
Here is the code for Gamepad API if you want to see it(Again, I'm aiming for Joy-Con motion controls):
var haveEvents = 'ongamepadconnected' in window;
var controllers = {};
function connecthandler(e) {
addgamepad(e.gamepad);
}
function addgamepad(gamepad) {
controllers[gamepad.index] = gamepad;
var d = document.createElement("div");
d.setAttribute("id", "controller" + gamepad.index);
var t = document.createElement("h1");
t.appendChild(document.createTextNode("gamepad: " + gamepad.id));
d.appendChild(t);
var b = document.createElement("div");
b.className = "buttons";
for (var i = 0; i < gamepad.buttons.length; i++) {
var e = document.createElement("span");
e.className = "button";
//e.id = "b" + i;
e.innerHTML = i;
b.appendChild(e);
}
d.appendChild(b);
var a = document.createElement("div");
a.className = "axes";
for (var i = 0; i < gamepad.axes.length; i++) {
var p = document.createElement("progress");
p.className = "axis";
//p.id = "a" + i;
p.setAttribute("max", "2");
p.setAttribute("value", "1");
p.innerHTML = i;
a.appendChild(p);
}
d.appendChild(a);
var start = document.getElementById("start");
if (start) {
start.style.display = "none";
}
document.body.appendChild(d);
requestAnimationFrame(updateStatus);
}
function disconnecthandler(e) {
removegamepad(e.gamepad);
}
function removegamepad(gamepad) {
var d = document.getElementById("controller" + gamepad.index);
document.body.removeChild(d);
delete controllers[gamepad.index];
}
function updateStatus() {
if (!haveEvents) {
scangamepads();
}
var i = 0;
var j;
for (j in controllers) {
var controller = controllers[j];
var d = document.getElementById("controller" + j);
var buttons = d.getElementsByClassName("button");
for (i = 0; i < controller.buttons.length; i++) {
var b = buttons[i];
var val = controller.buttons[i];
var pressed = val == 1.0;
if (typeof(val) == "object") {
pressed = val.pressed;
val = val.value;
}
var pct = Math.round(val * 100) + "%";
b.style.backgroundSize = pct + " " + pct;
if (pressed) {
b.className = "button pressed";
//Pressed down code here
} else {
b.className = "button";
//Release button code here
}
}
var axes = d.getElementsByClassName("axis");
for (i = 0; i < controller.axes.length; i++) {
var a = axes[i];
a.innerHTML = i + ": " + controller.axes[i].toFixed(4);
a.setAttribute("value", controller.axes[i] + 1);
}
}
requestAnimationFrame(updateStatus);
}
function scangamepads() {
var gamepads = navigator.getGamepads ? navigator.getGamepads() : (navigator.webkitGetGamepads ? navigator.webkitGetGamepads() : []);
for (var i = 0; i < gamepads.length; i++) {
if (gamepads[i]) {
if (gamepads[i].index in controllers) {
controllers[gamepads[i].index] = gamepads[i];
} else {
addgamepad(gamepads[i]);
}
}
}
}
window.addEventListener("gamepadconnected", connecthandler);
window.addEventListener("gamepaddisconnected", disconnecthandler);
if (!haveEvents) {
setInterval(scangamepads, 500);

Javascript: scope effect despite order of execution

Please note: This is not a question about scope, per se. I understand that in order to make the code work, I should make a deep copy of the variable board rather than assigning var tboard = board. However, I am not clear why making a shallow copy has the effect I describe below.
I am experiencing something I find baffling. Basically, a global variable (board) gets altered and I have no clue how. board is initialized in the function NewGame() (which is called from select()) as an empty array. After it is initialized, nothing else is called until the user clicks a square on the board (assuming the user has selected Xs for simplicity). When that happens, the function playerMove() is called. The baffling thing is that console.log(board) at the top of playerMove() prints out an array that has an x is the clicked position and os everywhere else (ie not empty). This is bizarre because the board is empty at the end of select() (which called NewGame()) and nothing else should happen in between. To demonstrate this, I print out the function name at the top of each function and I print out the board variable in the select() function and playerMove() function to show that it changes despite nothing else being called. Please note that to get this behavior, refresh the page (otherwise the board variable starts out full of os). I think this must be somewhat an issue of scope (because I am not making a deep copy of board) but it's strange because I have no clue what is being called that is changing the variable before it gets printed out at the top of playerMove().
Here is the link to my pen and the code: http://codepen.io/joshlevy89/pen/MKjxop?editors=101

Thanks in advance.

Simply add the break in the for loop fixes the problem. Am I missing anything?
function chooseMove(inboard) {
console.log('chooseMove');
// get the possible moves
var moves = [];
var scores = [];
for (var i = 1; i < 10; i++) {
var arr = PositionToCoords(i);
if (inboard[arr[0]][arr[1]] === undefined) {
moves.push(i);
var tboard = inboard;
tboard[arr[0]][arr[1]] = cSym;
var gc = gameCheck(tboard);
scores.push(gc);
break; // <<<<<<<<<<<< This break guarantees that the computer only makes one move
}
}
//console.log(moves);
//console.log(scores);
return moves[0]; // TEMPORARY
}

What is the Easiest way to fix the Ajax conflict error?

In my website (http://urlsaf.com/m8) I already added one Ajax based rating system but this system is not working properly. When ever I rate it, It's reloaded the page.

Javascript .Replace Alternative

I am coding a template for eBay. However, eBay does not allow .replace. The code below is for a rollover tab section.When the user hovers over tab(a), the correspodning div div(a) is made to become visible.
Is there a workaround to get the code to work without using .replace?
var divs = new Array();
divs.push("contentPayment");
divs.push("contentShipping");
divs.push("contentWarranty");
divs.push("contentContact");
var navs = new Array();

navs.push("nav3");
navs.push("nav4");

You may try this as an alternative of replace function
String.prototype.fakeReplace = function(str, newstr) {
return this.split(str).join(newstr);
};
var str = "Welcome javascript";
str = str.fakeReplace('javascript', '');
alert(str); // Welcome
DEMO.

For a more efficient, but slightly longer method, use this:
