| localeTitle: Modificar datos de matriz con índices
 | |

| 
 | |
| ## Description
 | |
| <section id="description"> A diferencia de las cadenas, las entradas de matrices son <dfn>mutables</dfn> y se pueden cambiar libremente. <strong>Ejemplo</strong> <blockquote> var ourArray = [50,40,30]; <br> ourArray [0] = 15; // es igual a [15,40,30] </blockquote> <strong>Nota</strong> <br> No debe haber espacios entre el nombre de la matriz y los corchetes, como la <code>array [0]</code> . Aunque JavaScript puede procesar esto correctamente, esto puede confundir a otros programadores que leen su código. </section>
 | |
| 
 | |
| ## Instructions
 | |
| <section id="instructions"> Modifique los datos almacenados en el índice <code>0</code> de <code>myArray</code> a un valor de <code>45</code> . </section>
 | |
| 
 | |
| ## Tests
 | |
| <section id='tests'>
 | |
| 
 | |
| ```yml
 | |
| tests:
 | |
|   - text: '<code>myArray</code> ahora debería ser [45,64,99].'
 | |
|     testString: 'assert((function(){if(typeof myArray != "undefined" && myArray[0] == 45 && myArray[1] == 64 && myArray[2] == 99){return true;}else{return false;}})(), "<code>myArray</code> should now be [45,64,99].");'
 | |
|   - text: Debe utilizar el índice correcto para modificar el valor en <code>myArray</code> .
 | |
|     testString: 'assert((function(){if(code.match(/myArray\[0\]\s*=\s*/g)){return true;}else{return false;}})(), "You should be using correct index to modify the value in <code>myArray</code>.");'
 | |
| 
 | |
| ```

 | |
| ourArray[1] = 45; // ourArray now equals [18,45,99].
 | |
| 
 | |
| // Setup
 | |
| var myArray = [18,64,99];
 | |
| 
 | |
| // Only change code below this line.
