Answer 1

вот это 'let txt = .....' нужно заключить в

<script type="text/javascript">
...
</script>

    <script ype="text/javascript">
    let txt = {
    en: {
    'aboutus':'• about us',
    'projects':'• projects',
    'skill':'• skill',
    'contacts':'• contacts'
    } ,ru: {
    'aboutus':'• о нас',
    'projects':'• проекты',
    'skill':'• скилы',
    'contacts':'• контакты'
    } ,ua: {
    'aboutus':'• про нас',
    'projects':'• проекти',
    'skill':'• скіли',
    'contacts':'• контакти'
    }
  };


const langEn = document.getElementById('e-lang-en');
const langRu = document.getElementById('e-lang-ru');
const langUa = document.getElementById('e-lang-ua');

langEn.addEventListener('click', setLang.bind(null, 'en'));
langRu.addEventListener('click', setLang.bind(null, 'ua'));
langUa.addEventListener('click', setLang.bind(null, 'ru'));

function setLang(lang){
    var e;
    if(!txt.hasOwnProperty(lang)) return;
    if(window.hasOwnProperty('localStorage'))
      window.localStorage.setItem('lang', lang);
     for(e in txt[lang]) {
      document.getElementById(e).innerText = txt[lang][e];
    }
  }
   
  var lang = (window.hasOwnProperty('localStorage') && window.localStorage.getItem('lang', lang)) || 'ru';
  setLang(lang);
</script>
