How to remove elements from an array with splice where there’s consecutive matches? [duplicate]

I have a function that removes vowels from a string, and then returns the string.
My problem is that where there’s two or more consecutive vowels it will only remove one of them. I can run the ‘for’ loop twice to fix the issues, but that doesn’t seem right. Is there anything I could change?

let string = "I'd always thought lightning was something only I could see.";
let vowels = ['a', 'e', 'i', 'o', 'u']

function removeVowels(str) {
  let stringArray = str.split('');
  for (let letter of stringArray){
    if (vowels.includes(letter.toLowerCase())){
      let index = stringArray.indexOf(letter); 
      stringArray.splice(index, 1);
  return stringArray.join('');
