如何通过值删除重复的数组元素并保留最新条目？

function removeDuplicates(arr) {
  var uniqueArray = [];
  
  arr.forEach(function(element) {
    var existingElement = uniqueArray.find(function(item) {
      return item.value === element.value;
    });
    
    if (!existingElement) {
      uniqueArray.push(element);
    } else if (element.timestamp > existingElement.timestamp) {
      var index = uniqueArray.indexOf(existingElement);
      uniqueArray[index] = element;
    }
  });
  
  return uniqueArray;
}

// 示例用法
var originalArray = [
  { value: 'A', timestamp: 1 },
  { value: 'B', timestamp: 2 },
  { value: 'A', timestamp: 3 },
  { value: 'C', timestamp: 4 },
  { value: 'B', timestamp: 5 }
];

var newArray = removeDuplicates(originalArray);
console.log(newArray);
