如何理解异步处理?什么时候使用?
this.book.ready.then(() => { return this.book.loacations.generate() }).then(res => { console.log(res) this.locations = this.book.loacations
() =>
res =>
这两个又有什么区别呢?
this.book.ready.then(() => { return this.book.loacations.generate() }).then(res => { console.log(res) this.locations = this.book.loacations
() =>
res =>
