1 | This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
2 |
3 | ## Available Scripts
4 |
5 | In the project directory, you can run:
6 |
7 | ### `yarn start`
8 |
9 | Runs the app in the development mode.
10 | Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
11 |
12 | The page will reload if you make edits.
13 | You will also see any lint errors in the console.
14 |
15 | ### `yarn test`
16 |
17 | Launches the test runner in the interactive watch mode.
18 | See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
19 |
20 | ### `yarn build`
21 |
22 | Builds the app for production to the `build` folder.
23 | It correctly bundles React in production mode and optimizes the build for the best performance.
24 |
25 | The build is minified and the filenames include the hashes.
26 | Your app is ready to be deployed!
27 |
28 | See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
29 |
30 | ### `yarn eject`
31 |
32 | **Note: this is a one-way operation. Once you `eject`, you can’t go back!**
33 |
34 | If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
35 |
36 | Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
37 |
38 | You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

63 | # Desafios
64 |
65 | ### Desafio 1
66 | O código abaixo está síncrono, você deve modificálo para que *callback1* seja chamado apenas uma vez depois de 2 segundos e *callback2* seja chamado 3 vezes com um intervalo de 1 segundo
67 |
68 | ```
69 | function job(callback1, callback2) {
70 | callback1();
71 |
72 | callback2();
73 | callback2();
74 | callback2();
75 | }
76 |
77 | ```
78 |
79 | [challenge](https://www.codingame.com/playgrounds/347/javascript-promises-mastering-the-asynchronous/some-pratice)
80 |
81 | ### Desafio 2
82 |
83 | Dado o código abaixo, a função job deve retornar um objeto de promise, a promise deve ser resolvida 2 segundos apóes invocar a função job e exibir um hello world
84 |
85 | ```
86 | function job() {
87 | return 'hello world';
88 | }
89 |
90 | ```
91 |
92 | ### Desafio 3
93 |
94 | Nesse código, sua função recebe um parâmetro. Você deve modificar o código abaixo com base nas seguintes regras:
95 |
96 | * Sua função deve sempre retornar uma promise
97 | * Se os dados não forem um número, retorne uma promise rejeitada instantaneamente e mostre o conteúdo do "erro"
98 | * Se os dados forem um número ímpar, retorne uma promise resolvida 1 segundo depois e exiba a mensagem "ímpar"
99 | * Se os dados forem um número par, retorne uma promise rejeitada 2 segundos depois e exiba a mensagem "par"
100 |
101 | ```
102 | function job(data) {
103 | return something;
104 | }
105 | ```
106 | [challenge](https://www.codingame.com/playgrounds/347/javascript-promises-mastering-the-asynchronous/more-pratice-with-promises)
107 |
108 | ### Desafio 4
109 |
110 | O código a seguir usa promises para manipular um resultado assíncrono. O resultado é uma promise que gera um ID quando resolvido. Esse ID deve ser usado para recuperar informações do banco de dados. No final, sua função deve retornar a propriedade *name* da informação. Em caso de erro, você deve retornar uma promise rejeitada com o erro fornecido. Mas primeiro você deve notificar o errorManager com o erro.
111 |
112 | ```
113 | function job(result, database, errorManager) {
114 | return result
115 |
116 | .then(function(id) {
117 | return database.get(id);
118 | })
119 |
120 | .then(function(info) {
121 | return info.name;
122 | })
123 |
124 | .catch(function(error) {
125 | errorManager.notify(error);
126 | throw error;
127 | });
128 | }
129 |
130 | module.exports = job;
131 | ```
