从对象数组中的属性创建对象

function createObjectFromProperties(array) {
  var newObj = {};
  
  for (var i = 0; i < array.length; i++) {
    var obj = array[i];
    
    for (var prop in obj) {
      if (obj.hasOwnProperty(prop)) {
        newObj[prop] = obj[prop];
      }
    }
  }
  
  return newObj;
}

// 示例用法
var array = [
  { name: 'John', age: 25, city: 'New York' },
  { name: 'Jane', age: 30, city: 'San Francisco' },
  { name: 'Bob', age: 35, city: 'Seattle' }
];

var result = createObjectFromProperties(array);
console.log(result);
