如何从字符串中删除/*和*/之间的字符

function removeComments(str) {
  let startIndex = str.indexOf("/*");
  let endIndex = str.indexOf("*/");

  while (startIndex !== -1 && endIndex !== -1) {
    let beforeComment = str.substring(0, startIndex);
    let afterComment = str.substring(endIndex + 2);
    str = beforeComment + afterComment;

    startIndex = str.indexOf("/*");
    endIndex = str.indexOf("*/");
  }

  return str;
}

let input = "This is a /* comment */ test string.";
let output = removeComments(input);
console.log(output);
