# --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`.
|
|
|
|
Using the words provided, check if the two sub-clauses of the phrase are plausible individually:
|
|
|
|
<ol>
|
|
<li>
|
|
<i>"I before E when not preceded by C".</i>
|
|
</li>
|
|
<li>
|
|
<i>"E before I when preceded by C".</i>
|
|
</li>
|
|
</ol>
|
|
|
|
If both sub-phrases are plausible then the original phrase can be said to be plausible.

# --instructions--
|
|
|
|
Write a function that accepts a word and check if the word follows this rule. The function should return true if the word follows the rule and false if it does not.
|
|
|
|
# --hints--
|
|
|
|
`IBeforeExceptC` should be a function.
|
|
|
|
```js
|
|
assert(typeof IBeforeExceptC == 'function');
|
|
```
|
|
|
|
`IBeforeExceptC("receive")` should return a boolean.
|
|
|
|
```js
|
|
assert(typeof IBeforeExceptC('receive') == 'boolean');
|
|
```
|
|
|
|
`IBeforeExceptC("receive")` should return `true`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('receive'), true);
|
|
```
|
|
|
|
`IBeforeExceptC("science")` should return `false`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('science'), false);
|
|
```
|
|
|
|
`IBeforeExceptC("imperceivable")` should return `true`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('imperceivable'), true);
|
|
```
|
|
|
|
`IBeforeExceptC("inconceivable")` should return `true`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('inconceivable'), true);
|
|
```
|
|
|
|
`IBeforeExceptC("insufficient")` should return `false`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('insufficient'), false);
|
|
```
|
|
|
|
`IBeforeExceptC("omniscient")` should return `false`.
|
|
|
|
```js
|
|
assert.equal(IBeforeExceptC('omniscient'), false);
|
|
```
