# --description--
|
|
|
|
**<a href="http://www.rosettacode.org/wiki/I_before_E_except_after_C" target="_blank" rel="noopener noreferrer nofollow">"I before E, except after C"</a>** is a general rule for English language spelling. If one is unsure whether a word is spelled with the digraph `ei` or `ie`, the rhyme suggests that the correct order is `ie` unless the preceding letter is `c`, in which case it may be `ei`.
|
|
|
|
Utilizando las palabras proporcionadas, verifica si las dos subcláusulas de la frase son plausibles individualmente:
|
|
|
|
<ol>
|
|
<li>
|
|
<i>"I before E when not preceded by C".</i>
|
|
</li>
|
|
<li>
|
|
<i>"E antes que I cuando esté precedido por C".</i>
|
|
</li>
|
|
</ol>
|
|
|
|
Si ambas subfrases son plausibles, entonces se puede decir que la frase original es plausible.

# --instructions--
|
|
|
|
Escribe una función que acepte una palabra y comprueba si la palabra sigue esta regla. La función debería devolver verdadero si la palabra sigue la regla y falso si no lo hace.
|
|
|
|
# --hints--
|
|
|
|
`IBeforeExceptC` debería ser una función.
|
|
|
|
```js
|
|
assert(typeof IBeforeExceptC == 'function');
|
|
```
|
|
|
|
`IBeforeExceptC("receive")` debería devolver un booleano.
|
|
|
|
```js
|
|
assert(typeof IBeforeExceptC('receive') == 'boolean');
|
|
```
|
|
|
|
`IBeforeExceptC("receive")` debería devolver `true`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('receive'), true);
|
|
```
|
|
|
|
`IBeforeExceptC("science")` debería devolver `false`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('science'), false);
|
|
```
|
|
|
|
`IBeforeExceptC("imperceivable")` debería devolver `true`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('imperceivable'), true);
|
|
```
|
|
|
|
`IBeforeExceptC("inconceivable")` debería devolver `true`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('inconceivable'), true);
|
|
```
|
|
|
|
`IBeforeExceptC("insufficient")` debería devolver `false`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('insufficient'), false);
|
|
```
|
|
|
|
`IBeforeExceptC("omniscient")` debería devolver `false`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('omniscient'), false);
|
|
```
