— GetElementsBy* -> NodeList
getElementBy* -> Element

Sorry guys.. It's a typo.. After some testing.. This is what is Working for me
var elements=document.getElementsByClassName("test")
console.log(elements)
for(var i=0;i<elements.length;i++){
elements[i].innerText=elements[i].innerHTML.toUpperCase()
}

— You can remove the console code...

— The line
elements[i].innerText=elements[i].innerHTML.toUpperCase()

— Can also and should be
elements[i].innerHTML=elements[i].innerHTML.toUpperCase()

—

Array.from(document.getElementsByClassName('test'))
  .forEach(element =>
    element.textContent =
      element.textContent.toUpperCase());

— Mh...thats cool...I tried the map and forEach and the browser could not allow it...creating an array from it is new to me...but it works!!

— For testing purposes, the first line should be ....Array.from(document.getElementsByClassName('test'))...

— Instead of Array.from, you can also do:
[...getElementsByClassName('test')]

— Ahh yes

— [...stuffToArray] looks better imo
