Search bar that can change language

Im very new to JavaScript so i don’t know if this is even possible. I have a searchbar with an autocomplete function and i also have a few buttons that can change my websites language:

//searchbar//
let availableKeywords = [
  'example1',
  'exapmle2',
  'example3'
];

const resultsBox = document.querySelector(".result-box");
const inputBox = document.getElementById("query");

inputBox.onkeyup = function(){
  let result = [];
  let input = inputBox.value;
  if(input.length){
    result = availableKeywords.filter((keyword)=>{
      return keyword.toLowerCase().includes(input.toLowerCase());
    });
    console.log(result);
  }
  display(result);

  if(!result.length){
    resultsBox.innerHTML = '';
  }
}

function display(result){
  const content = result.map((list)=>{
    return "<li onclick=selectInput(this)>" + list + "</li>";
  });

  resultsBox.innerHTML = "<ul>" + content.join('') + "</ul>";
}

function selectInput(list){
  inputBox.value = list.innerHTML;
  resultsBox.innerHTML = '';
}

//buttons//
const langEl = document.querySelector(".langWrap");

link.forEach((el) => {
  el.addEventListener("click", () => {
    langEl.querySelector(".active").classList.remove("active");
    el.classList.add("active");
});

I was wondering if it was possible that the content of availableKeywords could change language depending on wich language button is active?
