## Description
|
|
<section id="description"> A veces necesitarás construir una cadena, al estilo de <a href="https://en.wikipedia.org/wiki/Mad_Libs" target="_blank">Mad Libs</a> . Al utilizar el operador de concatenación ( <code>+</code> ), puede insertar una o más variables en una cadena que está creando. </section>
|
|
|
|
## Instructions
|
|
<section id="instructions"> Establezca <code>myName</code> en una cadena igual a su nombre y compile <code>myStr</code> con <code>myName</code> entre las cadenas <code>"My name is "</code> y <code>" and I am well!"</code> </section>
|
|
|
|
## Tests

|
<section id='tests'>
|
|
|
|
```yml
|
|
tests:
|
|
- text: <code>myName</code> debe establecerse en una cadena de al menos 3 caracteres
|
|
testString: 'assert(typeof myName !== "undefined" && myName.length > 2, "<code>myName</code> should be set to a string at least 3 characters long");'
|
|
- text: Usa dos operadores <code>+</code> para construir <code>myStr</code> con <code>myName</code> dentro de él
|
|
testString: 'assert(code.match(/[""]\s*\+\s*myName\s*\+\s*[""]/g).length > 0, "Use two <code>+</code> operators to build <code>myStr</code> with <code>myName</code> inside it");'
