一、理解函数式编程

1. 有一个Web服务，为你提供了如下的数据结构：

难度：★

var data = [
  {
    name: "Jamestown",
    population: 2047,
    temperatures: [-34, 67, 101, 87]

},

使用Node.JS （版本>= 8)完成下题：

假设系统提供了三个函数：

• Project.create({name: 'P1', ownerId: 1}) 函数
  在数据库中的Project表中创建一条记录。函数返回一个Promise对象。resolve方法的参数是一个Project对象：{id: 1, name: 'P1', ownerId: 1}。
• Task.create({projectId: 1, title: 'T1', assignTo: 1})函数
  在数据库中的Task表中创建一条子记录。这个记录通过projectId和Project表关联。函数返回Promise对象，resolve对象例如：{id: 1, projectId: 1, title: 'T1', assignTo: 1}
• User.create({name: 'U1'})函数
  在数据库中的User表中创建一条记录。{id: 1, name: 'U1'}
