2.一些CSS
3.一个计时器。
2.一些CSS
3.一个计时器

1. 关于JS和Async JS的一般问题。
   2.一些简单的对象操作和承诺的使用（通过使用setTimeout来模拟一个假的后端）。
   3. A text based snake
   4. 一些基本的CSS
   5. 一个带有复位按钮的计时器
   Promise.resolve
   var, const ,let的区别；异步和同步代码的执行原理；new Map, new Set, Promise, spread操作符，.size，Math这些API的使用
   实现fetch、ajax
   得到的数据中，求出shapes所包含的所有shapeId的color的平均值, ```javascript function fetch(id) {

   return new Promise(resolve => {

   setTimeout(() => resolve({

   designId: id,

   shapes: [

   {shapeId: 'basic-shape', color: { r: 55, g: 40, b: 255 }, children: []},
   {shapeId: 'duck', color: { r: 255, g: 255, b: 252 }, children: [
    {shapeId: 'duck-bill', color: { r: 255, g: 255, b: 255 }, children: []},
    {shapeId: 'duck-body', color: { r: 205, g: 255, b: 252 }, children: []},
    {shapeId: 'duck-legs', color: { r: 100, g: 255, b: 252 }, children: []},
   ]},
   {shapeId: 'zigzag-polygon', color: { r: 205, g: 255, b: 252 }, children: []},
   {shapeId: 'fish', color: { r: 205, g: 255, b: 252 }, children: [
    {shapeId: 'fish-eyes', color: { r: 255, g: 255, b: 255 }, children: []},
    {shapeId: 'fish-fin', color: { r: 100, g: 66, b: 74 }, children: [
     {shapeId: 'fish-fin-part-1', color: { r: 93, g: 54, b: 55 }, children: []},
     {shapeId: 'fish-fin-part-2', color: { r: 33, g: 255, b: 255 }, children: []},
     {shapeId: 'fish-fin-part-3', color: { r: 128, g: 53, b: 255 }, children: []},
    ]},
    {shapeId: 'fish-tail', color: { r: 255, g: 5, b: 255 }, children: []},
   ]},
   {shapeId: 'duck', color: { r: 255, g: 255, b: 252 }, children: [
    {shapeId: 'duck-bill', color: { r: 255, g: 255, b: 255 }, children: []},
    {shapeId: 'duck-body', color: { r: 205, g: 255, b: 252 }, children: []},
    {shapeId: 'duck-legs', color: { r: 100, g: 255, b: 252 }, children: []},
   ]},

   ]

   }), Math.random() * 4000);

   });

}

// output

// “Design: {id}, color: { r: 1, g: 2, b: 3 }” ```
