## Description
|
||
|
|
<section id='description'>
|
||
|
|
orden es importante en <code>if</code> , <code>else if</code> declaraciones.
|
||
|
|
La función se ejecuta de arriba a abajo, por lo que deberá tener cuidado con la afirmación que aparece primero.
|
||
|
|
Toma estas dos funciones como ejemplo.
|
||
|
|
Aquí está el primero:
|
||
|
|
<blockquote>function foo(x) {<br> if (x < 1) {<br> return "Less than one";<br> } else if (x < 2) {<br> return "Less than two";<br> } else {<br> return "Greater than or equal to two";<br> }<br>}</blockquote>
|
||
|
|
Y el segundo solo cambia el orden de las declaraciones:
|
||
|
|
<blockquote>function bar(x) {<br> if (x < 2) {<br> return "Less than two";<br> } else if (x < 1) {<br> return "Less than one";<br> } else {<br> return "Greater than or equal to two";<br> }<br>}</blockquote>
|
||
|
|
Si bien estas dos funciones parecen casi idénticas, si pasamos un número a ambas obtenemos diferentes salidas.
|
||
|
|
<blockquote>foo(0) // "Less than one"<br>bar(0) // "Less than two"</blockquote>
|

## Instructions
|
||
|
|
<section id='instructions'>
|
||
|
|
Cambie el orden de la lógica en la función para que devuelva las declaraciones correctas en todos los casos.

|
- text: <code>orderMyLogic(11)</code> debe devolver "Mayor o igual a 10"
