Edit:
I have made some changes in the code.
How can I remove the eventlistener from the clicked buttons ?

Answer 1

getElementsByClassName returns a node list of "elements" so you need to specify by indexing which element you are referring to like ele[0] ,also you need to put your js code inside window.onload function

window.onload=function(){
Js code
}

Answer 2

Hima add "this" instead of ele[0]
this.removeEventListener('click',fun);

Answer 3

Hima I think this does the work !!

function fun()
{
console.log("hello");
if(this.classList[1]=="match" & count==0){
count=1;
}
else if(this.classList[1]=="match" & count==1){

for(i of deck.children){
if(i.classList[1]=="match"){
i.removeEventListener('click',fun);
}
}

count=0;
}
else{
this.removeEventListener('click',fun);
count=0;
}

}

Answer 4

So what you want to do? If one button with class match is clicked remove event listener from other button as well with same class?
