| ## Description
 | |
| <section id="description"> Es posible tener variables <dfn>locales</dfn> y <dfn>globales</dfn> con el mismo nombre. Cuando haces esto, la variable <code>local</code> tiene prioridad sobre la variable <code>global</code> . En este ejemplo: <blockquote> var someVar = "Hat"; <br> función myFun () { <br> var someVar = "Head"; <br> devuelve someVar; <br> } </blockquote> La función <code>myFun</code> devolverá <code>"Head"</code> porque la versión <code>local</code> de la variable está presente. </section>
 | |
| 
 | |
| ## Instructions
 | |
| <section id="instructions"> Agregue una variable local a la función <code>myOutfit</code> para anular el valor de <code>outerWear</code> con <code>"sweater"</code> . </section>
 | |
| 
 | |
| ## Tests
 | |
| <section id='tests'>
 | |
| 
 | |
| ```yml
 | |
| tests:
 | |
|   - text: No cambie el valor de la <code>outerWear</code> global
 | |
|     testString: 'assert(outerWear === "T-Shirt", "Do not change the value of the global <code>outerWear</code>");'
 | |
|   - text: <code>myOutfit</code> debe devolver <code>"sweater"</code>
 | |
|     testString: 'assert(myOutfit() === "sweater", "<code>myOutfit</code> should return <code>"sweater"</code>");'
 | |
|   - text: No cambie la declaración de devolución
 | |
|     testString: 'assert(/return outerWear/.test(code), "Do not change the return statement");'
