如何克隆数组以具有可选的true和false字段？

function cloneArrayWithOptionalFields(arr) {
  var clonedArray = [];
  
  for (var i = 0; i < arr.length; i++) {
    var clonedObj = Object.assign({}, arr[i]);
    clonedObj.true = true;
    clonedObj.false = false;
    clonedArray.push(clonedObj);
  }
  
  return clonedArray;
}

// 示例用法
var originalArray = [{name: "John"}, {name: "Jane"}, {name: "Bob"}];
var clonedArray = cloneArrayWithOptionalFields(originalArray);
console.log(clonedArray);
