VistasSmooth toggle Javascript function
Well what I want to do is to toggle a menu when is clicked but it's not smooth and it feels tough, I'm a newbie in JS but I do know CSS and HTML well enough, so is there a way to smooth this toggle function?
menu unclicked:
menu clicked:
const toggleButton = document.getElementsByClassName("nav__toggle-button")[0];
const navbarLinks = document.getElementsByClassName("nav__links")[0];
toggleButton.addEventListener("click", () => {
console.log("clicked");
navbarLinks.classList.toggle("active");
toggleButton.classList.toggle("open");
});

You can apply transition and transform properties to the element through CSS. For example, if you are using a drop down menu and controlling the slide and the opacity:
transform: translateY(-10px);
transition: opacity 150ms ease-in-out, transform 150ms ease-in-out;
You could check out: https://developer.mozilla.org/en-US/docs/Web/CSS/transition

If you want to solve this with CSS you can 'animate' the two divs with the transitions property: https://www.w3schools.com/css/css3_transitions.asp
close state:
div {
opacity: 0;
transition: opacity 1s;
}
open state:
div.active {
opacity: 1;
transition: opacity 1s;
}
Two minors:
don't use BEM classes to trigger an event listener, use instead a proper class (js-click or something..)
a small refactor for your first two lines:
const [toggleButton] = document.querySelectorAll(".nav__toggle-button")
const [navbarLinks] = document.querySelectorAll(".nav__links")

All you need is a transition and transform property that you can toggle. Transform CSS property is used for handling dimensions, orientation etc of a DOM element. Adding transition adds an effect where the transform properties if changed, change gradually.
const closeButton = document.getElementById("close")
closeButton.addEventListener("click", () => {
const menu = document.getElementById("nav-links")
menu.classList.toggle("closed-list");
})ol {
width: 100%;
list-style-type: none;
background: gray;
transition: all 0.4s ease-in-out;
}
.closed-list {
transform: scaleY(0);
transform-origin: top;
}
li {
text-align: center;
padding: 12px 0px;
color: white;
font-weight: 700;
font-size: 18px;
}
#close-container {
text-align: right;
}<div>
<div id="close-container">
<button id="close">
open/close
</button>
</div>
<ol id="nav-links">
<li>Test 1</li>
<li>Test 2</li>
<li>Test 3</li>
<li>Test 4</li>
</ol>
</div>
