I wrote this code in my html file <button onclick="startGame" class="startBtn">Start</button>

And this in my JavaScript


var start = document.querySelector(".starter");

var game = document.querySelector(".game");

var submit = document.querySelector(".submit");

function startGame() {

  start.classList.add("hide");

  game.classList.remove("hide");

}

But when I run this it shows the error like this enter image description here

I tried to hide an element and show another with this function. But return the error

looks like start variabel didn't find your element. try console.log(start) to check does it get the html element or not
