接口，都可以采用数组形式的解构赋值。 变量的解构赋值 47 function* fibs() { let a = 0; let b = 1; while (true) { yield a; [a, b] = [b, a + b]; } } let [first, second, third, fourth, fifth, sixth] = fibs(); （2）不可以当作构造函数，也就是说，不可以使用 new 命令，否则会抛出一个错 误。 （3）不可以使用 arguments 对象，该对象在函数体内不存在。如果要用，可以 用 rest 参数代替。 （4）不可以使用 yield 命令，因此箭头函数不能用作 Generator 函数。 上面四点中，第一点尤其值得注意。 this 对象的指向是可变的，但是在箭头函数 中，它是固定的。 function foo() { 2, 3] Generator 函数运行后，返回一个遍历器对象，因此也可以使用扩展运算符。 数组的扩展 173 var go = function*(){ yield 1; yield 2; yield 3; }; [...go()] // [1, 2, 3] 上面代码中，变量 go 是一个 Generator 函数，执行后返回的是一个遍历器对象， 对这个遍历器

supporting use full ES6/7 features to develop Node.js application. By using async/await in ES7 or */yield in ES6, ThinkJS totally resovled the hard problem of asynchronous callbacks nesting hell. It absorbs browser compatibility. So we can resolve the asynchronous callbacks problem by using async/await or */yield features. We’ve used ES6 features like class , export , let and ES7 features like async/await efficient. Koa 1.x solved asynchronous callbacks problem by using */yield feature. But the newer async/await feature will replace */yield at last. ThinkJS supports both features well. On the other hand
