将字符串中的结束括号替换为反斜杠字符后跟结束括号

function replaceEndBracket(str) {
  let result = '';
  for (let i = 0; i < str.length; i++) {
    if (str[i] === ')') {
      result += '\\)';
    } else {
      result += str[i];
    }
  }
  return result;

const inputString = '将字符串中的结束括号替换为反斜杠字符后跟结束括号)';
const replacedString = replaceEndBracket(inputString);
console.log(replacedString);
