<--- JS …

假设我有一个对象数组：

let arr = [
   {
    name: 'Jack',
    id: 1
   },
   {
    name: 'Gabriel',
    id: 2
   },
   {
    name: 'John',
    id: 3
   }
]

我需要检查该数组是否包含名称“Jack”，例如使用：

if (arr.includes('Jack')) {
   // don't add name to arr

} else {
  // push name into the arr

}

但是 arr.includes('Jack') 返回 false，如何检查对象数组是否包含名称？
