Removing event listener from a tile of sudoku game

I`m trying to remove event listener from a tile that has been filled correctly on a sudoku game. But it is not working. After i fill the correct number on slot, i wish i wouldnt be able to click it again, but happens as the GIF show, it is erasing the grayed slots, meaning that removeEventListener is not working correctly. Any Help?
function qsa(selector) {
return document.querySelectorAll(selector);
}
function removeListenTiles() {
let tiles = qsa("tile");
for (let i = 0; i < tiles.length; i++) {
if (tiles[i].innerHTML.indexOf("table") == -1) {
if (tiles[i].textContent != "") {
tiles[i].removeEventListener("click", () => handleTile(tile[i), true);
}
}
}
}
function handleTile(tile) {
if (!disableSelect) {
if (tile.classList.contains("selected")) {
removeAllGrayedSelected();
updateMove();
removeSelected(tile);
selectedTile = null;
selectedNum = null;
} else {
removeAllGrayedSelected();
if (tile.innerHTML.indexOf("table") != -1) {
for (let j = 0; j < 81; j++) {
if (qsa(".tile")[j] !== tile) removeSelected(qsa(".tile")[j]);
}
tile.classList.add("selected");
selectedTile = tile;
updateSurround(tile);
updateMove();
}
}
}
}
function addListenTile(tile) {
tile.addEventListener("click", () => handleTile(tile), true);
}

Tried the currying method,and added tile.id to handlers array. Solved the problem.
const handlers = [];
const addListenTile = (tile) => {
tile.addEventListener("click", handlers[tile.id] = handleTile(tile), true);
};
const removeListenTile = (tile) => {
tile.removeEventListener("click", handlers[tile,id], true);
}
const handleTile = function (tile) {
return function onhandlerTile(event) {
console.log("OK1")
if (!disableSelect) {
if (tile.classList.contains("selected")) {
console.log("OK2");
removeAllGrayedSelected();
updateMove();
removeSelected(tile);
selectedTile = null;
selectedNum = null;
} else {
console.log("OK3");
removeAllGrayedSelected();
if (tile.innerHTML.indexOf("table") != -1) {
for (let j = 0; j < 81; j++) {
if (qsa(".tile")[j] !== tile) removeSelected(qsa(".tile")[j]);
}
tile.classList.add("selected");
selectedTile = tile;
updateSurround(tile);
updateMove();
}
}
}
};
};

How to pause the entire code for 1 second in javascript

I am trying to code an evolutionary neural network for the game snake. I already coded the neural network part and now I'd like to output the game of the best individual of every generation. For that I'm using the drawing library p5.js (https://p5js.org/).
In my code I am running a loop in where a new generation based on the last generation is created. Each individual of the generation will have to play the game and that is how they are rated. Now I want the best individual to be outputted after I let every individual play once.
Between each outputted turn of the game of the best individual I want the code to wait 500 milliseconds. How do I achieve that?
Here is the code I've already tried but here it only outputed the board after the last turn of each generation:
async function start() {
for (let i = 0; i < 50; i++) {
population.createNewGeneration();
let bestGameTurns = population.bestIndividual.game.turns; //Array of boards
for (let turn = 0; turn < bestGameTurns.length; turn++) {
let board = bestGameTurns[turn];
drawBoard(board);
let p = new Promise(resolve => setTimeout(resolve, 500));
await p;
function drawBoard(board) {
//Draw the board using p5.js rect()'s
}
}
}
}
Another version but the waiting didn't work here:
let i = 0;
setInterval(async () => {
population.createNewGeneration();
console.log(i, population.avgFitness);
let bestGameTurns = population.bestIndividual.game.turns; //Array of boards
for (let turn = 0; turn < bestGameTurns.length; turn++) {
let board = bestGameTurns[turn];
drawBoard(board);
let p = new Promise(resolve => setTimeout(resolve, 500));
await p;
function drawBoard(board) {
//Draw the board using p5.js rect()'s
}
}
i++;
}, 1);

The code you provided should do what you asked for, I could only clean up some parts for you. Explain a bit better what is the problem you are facing.
// The function should be defined only once.
function drawBoard(board) { }
async function start() {
for (let i = 0; i < 50; i++) {
population.createNewGeneration();
const bestGameTurns = population.bestIndividual.game.turns; //Array of boards
for (let turn = 0; turn < bestGameTurns.length; turn++) {
// Don't wait on first iteration
await new Promise(resolve => setTimeout(resolve, 500 * (turn ? 0 : 1 )));
drawBoard(bestGameTurns[turn]);
}
}
}

Original idea (discarded)
You can create a short function like that:
function pause(ms) {
return new Promise((resolve) => setTimeout(resolve, ms));
}
Then in any async function you can call it like that:
async function () {}
// something happening
await pause(500);
// continue
}
The other idea
Now, the code in your question is not complete so this is kind of blind coding but.
So, first of all setInterval will be running the whole function every 1 millisecond (actually 4 ms, as this is the minimum in JS). Which means it will run those loops. I decided to focus on the part that was marked by you.
Instead of loop and trying to pause it, I ask that maybe rewriting the loop into function called each half second until condition is met would do?
Also, I move drawBoard outside
setInterval(async () => {
// ^^^^^^^^ <-- this should probably go
population.createNewGeneration();
console.log(i, population.avgFitness);
let bestGameTurns = population.bestIndividual.game.turns; //Array of boards
function tick(turn = 0) {
let board = bestGameTurns[turn];
function drawBoard(board) {
//Draw the board using p5.js rect()'s
}
drawBoard(board);
// here is "setTimeouted" loop
if (turn < bestGameTurns.length) {
setTimeout(tick, 500, turn + 1);
}
}
tick();
}, 1);

Thanks to everyone, your suggestions brought me to an idea. I found out that the problem was lying somewhere else. Because javascript only runs on the one thread (I think thats how its called), after we run over one generation, we have to stop that function to let another draw function, which runs every frame, draw the board. After it is drawn, the main function can continue. This is how it looks:
let isDrawn = false;
let currentBoard;
async function setup() {
for (let i = 0; i < 50; i++) {
population.createNewGeneration();
const bestGameTurns = population.bestIndividual.game.turns;
for (let turn = 0; turn < bestGameTurns.length; turn++) {
await step(bestGameTurns[turn], turn);
}
}
}
function step(board, turn) {
currentBoard = board;
isDrawn = false;
return new Promise(resolve => setTimeout(() => {
if (isDrawn) resolve();
}, 500));
}
setTimeout(() => {
if (currentBoard) {
drawBoard(currentBoard);
isDrawn = true;
currentBoard = undefined;
}
}, 1);

let population;
let game;
let isDrawn = false;

}

It's not working that well but a few improvements should make it better...
If you have any suggestions for improvements of the code, please let me know!

I tried to fix it into steps as I said in comments,I hope I have no mistake :
let i = 0;
async function step(bestGameTurns, turn)
{
if (turn == bestGameTurns.length)
return;
let board = bestGameTurns[turn];
drawBoard(board);
let p = new Promise(resolve => setTimeout(() => step(bestGameTurns, turn+1), 500));
await p;
}
function drawBoard(board) {
//Draw the board using p5.js rect()'s
}
setInterval(async () => {
population.createNewGeneration();
console.log(i, population.avgFitness);
let bestGameTurns = population.bestIndividual.game.turns; //Array of boards
step(bestGameTurns, 0);
i++;
}, 1);

No matter how am i trying to do it. for somereason i can't change the clickedSpots Array.. it does recognize the array but i can't change the data. i cant push into it. and i can't change the data inside it. Line : 49 is , clickedPos[i] = 1. any one have a solution to this problem ? i'm really desperate. i tried couple of things and none of them are working.

I can't figure out why it's saying that the matcher function is undefined.

This code is designed to identify an array of anagrams for a string given an array of possible anagrams.
var anagram = function(input) {
return input.toLowerCase();
}
I'm adding the matcher function here to the String prototype.
String.prototype.matcher = function(remainingLetters) {
var clone = this.split("");
for (var i = 0; i < clone.length; i++) {
if (clone[i].indexOf(remainingLetters) > -1) {
remainingLetters.splice(clone[i].indexOf(remainingLetters, 1));
clone.splice(i, 1);
}
}
if (remainingLetters.length == 0 && clone.length == 0) {
return true;
}
else {
return false;
}
}
a
String.prototype.matches = function(matchWordArray) {
var result = [];
for (var i = 0; matchWordArray.length; i++) {
var remainingLetters = this.split("");
if (matchWordArray[i].matcher(remainingLetters)) {
result.push(arrayToMatch[i]);
}
}
return result;
}
var a = anagram("test");
a.matches(["stet", "blah", "1"]);
module.exports = anagram;

Should probably be:
for (var i = 0; i < matchWordArray.length; i++) {
The original statement:
for (var i = 0; matchWordArray.length; i++) {
...would result in an infinite loop because matchWordArray.length is always truthy (3) in your test.

Is there a single function to check an array contains another array?

[1,2,3].CONTAINS([1,2]) ==> true
[1,2,3].CONTAINS([1,2,3,4]) ==> false
or
{a:1,b:2,c:3}.HASKEYS([a,b]) ==> true
{a:1,b:2,c:3}.HASKEYS([a,b,c,d]) ==> false
Is there a single function to check an array contains another array?

No, but you can make one:
Array.prototype.contains = function(other) {
for (var i = 0; i < other.length; i++) {
if (this.indexOf(other[i]) === -1) return false;
}
return true;
}
And if order matters:
Array.prototype.contains = function(other) {
var broken;
if (!other.length) return true;
for (var i = 0; i < this.length - other.length + 1; i++) {
broken = false;
for (var j = 0; j < other.length; j++) {
if (this[i + j] !== other[j]) {
broken = true;
break;
}
}
if (!broken) return true;
}
return false;
}
The other function is similar, so I'll leave it to you to finish:
Object.prototype.has_keys = function(keys) {
...
}
