 # Tutorial Master JavaScript de 4Geeks Academy

 ### 160 ejercicios de JavaScript

 Selección completa de ejercicios de JavaScript interactivos y con calificación automática, donde pondrás tus habilidades de resolución de problemas al límite y aprenderás muchos de los métodos más populares de JavaScript.

 > Un punto clave para aprender en el mundo de la programación es que el mismo problema puede tener varias soluciones válidas, lo importante que debes entender es la lógica y los principios detrás de cada solución.

 <!-- hide -->

 ## Instalación en un clic (recomendado)

 Puedes empezar estos ejercicios en pocos segundos haciendo clic en: [Abrir en Codespaces](https://codespaces.new/?repo=4GeeksAcademy/master-javascript-programming-exercises) (recomendado) o [Abrir en Gitpod](https://gitpod.io#https://github.com/4GeeksAcademy/master-javascript-programming-exercises).

 > Una vez ya tengas abierto VSCode los ejercicios deberían empezar automáticamente, si esto no sucede puedes intentar empezar los ejercicios escribiendo este comando en tu terminal: `$ learnpack start`

 ## Instalación local

 Clona el repositorio en tu ambiente local y sigue los siguientes pasos:

 1. Instala LearnPack, el package manager para los tutoriales interactivos y el node compiler plugin para LearnPack, asegúrate también de tener node.js 14:

 ```bash
 $ npm i @learnpack/learnpack -g
 ```

 2. Inicializa el tutorial/exercises ejecutando el siguiente comando al mismo nivel en el que se encuentra tu archivo learn.json:

 ```bash
 $ learnpack start
 ```

 <!-- endhide -->

 ## ¿Cómo están organizados estos ejercicios?

 Cada ejercicio es una pequeña aplicación de React que contiene los siguientes archivos:

 - **app.js**: Representa el archivo JavaScript de entrada que ejecutará la computadora.
 - **README.md**: Contiene las instrucciones del ejercicio.
 - **test.js**: Contiene el script del test para el ejercicio (no es necesario que abras este archivo).

 > Nota: Estos ejercicios tienen calificación automática. Los tests son muy rígidos y estrictos, mi recomendación es que no prestes demasiada atención a los tests y los uses solo como una sugerencia o podrías frustrarte.

 ### 160 exercises about JavaScript

 Complete selection of auto-graded and interactive JavaScript exercises, where you will put your problem-solving skills to the test and learn many of the most popular JavaScript methods.

 > One key thing to learn in the world of coding is that the same problem may have multiple valid solutions, the important thing is that you understand the logic and principles behind them.

 <!-- hide -->

 ## One click installation (recommended):

 You can open these exercises in just a few seconds by clicking: [Open in Codespaces](https://codespaces.new/?repo=4GeeksAcademy/master-javascript-programming-exercises) (recommended) or [Open in Gitpod](https://gitpod.io#https://github.com/4GeeksAcademy/master-javascript-programming-exercises).

 > Once you have VSCode open, if exercises don't run automatically you can try typing on your terminal: `$ learnpack start`

 ## Local Installation (only if needed)

 Clone the repository in your local environment and follow the steps below:

 1. Install LearnPack, the package manager for learning tutorials and the node compiler plugin for learnpack, make sure you also have node.js 14:

 ```bash
 $ npm i @learnpack/learnpack -g
 ```

 2. Start the tutorial/exercises by running the following command at the same level where your learn.json file is:

 ```bash
 $ learnpack start
 ```
 <!-- endhide -->

 ## How are the exercises organized?

 Each exercise is a small React application containing the following files:

 1. **app.js**: Represents the entry JavaScript file that will be executed by the computer.
 2. **README.md**: Contains exercise instructions.
 3. **test.js**: Contains the testing script for the exercise (you don't have to open this file).

 > Note: The exercises have automatic grading, but it's very rigid and strict, my recommendation is to not take the tests too serious and use them only as a suggestion, or you may get frustrated.
