No it don't require to use it multiple times
See Updated Code:
<script>
let menu
require(['jquery', 'jquery/ui'], function($){
$.ajax({
url: "https://catfact.ninja/fact",
context: document.body
}).done(function(value) {
menu = []
menu.forEach(element => {
$('.mainMenu').append("<div class='menuContainer menuNumber" + element.id + "'>" + element.name + "</div>")
});
});
function openMainMenu(){
$('.mainMenu').show();
}
function openCategory(categoryNumber){
console.log($('.menuNumber' + categoryNumber).css("visibility", "visible"));
}
});
</script>
