## Description
|
|
<section id="description"> Puede encontrar la longitud de un valor de <code>String</code> escribiendo <code>.length</code> después de la variable de cadena o el literal de cadena. <code>"Alan Peter".length; // 10</code> Por ejemplo, si creamos una variable <code>var firstName = "Charles"</code> , podríamos averiguar cuánto tiempo dura la cadena <code>"Charles"</code> utilizando la propiedad <code>firstName.length</code> . </section>
|
|
|
|
## Instructions
|
|
<section id="instructions"> Utilice la propiedad <code>.length</code> para contar el número de caracteres en la variable <code>lastName</code> y asignarla a <code>lastNameLength</code> . </section>
|
|
|
|

|
|
- text: 'Que debería estar recibiendo la longitud de <code>lastName</code> utilizando <code>.length</code> así: <code>lastName.length</code> .'
