如何从获取的嵌套数组中去掉括号

function removeBrackets(arr) {
  var result = [];
  
  for (var i = 0; i < arr.length; i++) {
    var element = arr[i];
    
    if (typeof element === 'string') {
      if (element.startsWith('(') && element.endsWith(')')) {
        element = element.slice(1, -1);
      }
    }
    
    if (Array.isArray(element)) {
      element = removeBrackets(element);
    }
    
    result.push(element);
  }
  
  return result;
}

// 示例用法
var nestedArray = [
  'one',
  '(two)',
  ['(three)', 'four', ['five', '(six)', 'seven']],
  'eight'
];

var result = removeBrackets(nestedArray);
console.log(result);
