使用Javascript for HTML使变量大写的第一个字母

Question

我正在尝试使用'innerHTML'打印出我的结果>

  if (userChoice === computerChoice) {
    console.log("Tie!");
    result_h3.innerHTML =
      userChoice + " and " +
      computerChoice +
      " are both the same. It's a draw!";
如何使userChoice变量的首字母在浏览器中大写？

我尝试过：

  if (userChoice === computerChoice) {
    console.log("Tie!");
    result_h3.innerHTML =
      userChoice.value.charAt(0).toUpperCase() +
      userChoice.value.slice(1).toLowerCase() +
      +" and " +
      computerChoice +
      " are both the same. It's a draw!";
没有用。

我正在尝试使用'innerHTML'打印我的结果，如果（userChoice === computerChoice）{console.log（“ Tie！”）; result_h3.innerHTML = userChoice +“和” + computerChoice + ...
