how i can make burger menu toggle by javascript

Question

I'm an absolute beginner in javascript I want to open and close the burger menu. I don't know why it doesn't work with me. When I write .open{display:block} it shows up and I can't even open or close the burger menu how I can fix this and why it shows up like this ? here the code:

let btn = document.getElementById('btn-js');
let sidebar = document.getElementById('side-bar');

btn.addEventListener('click',show());

function show(){
    sidebar.classList.toggle('open');
}

*{
    margin: 0;
    padding:0;
    box-sizing: border-box;
    list-style: none;
}


.side-bar{
    display: none;
    background: cornflowerblue;
    width: 275px;
    text-align: center;
    font-size: 19px;
    

}

.side-links{
    padding: 30px 0;
}

.side-links li{
    padding: 30px 0;
}


@media all and (max-width:800px) {

    .open{
        display: block;
    }
}

`addEventListener` expects a function as its second argument. `show()` isn’t a function. — Sebastian Simon, Sep 13 '21 at 01:40
Try removing the parenthesis when calling show like this `btn.addEventListener('click', show);` — Ronniel Sembrano, Sep 13 '21 at 04:36
