## Description
<section id='description'>
<code>if/else</code> утверждения могут быть объединены вместе для сложной логики. Вот <dfn>псевдокод</dfn> операторов с несколькими цепями <code>if</code> / <code>else if</code> : <blockquote> если ( <em>условие 1</em> ) { <br> <em>statement1</em> <br> } else if ( <em>условие2</em> ) { <br> <em>оператор2</em> <br> } else if ( <em>условие 3</em> ) { <br> <em>оператор3</em> <br> , , , <br> } else { <br> <em>statementN</em> <br> } </blockquote>
</section>
## Instructions
<section id='instructions'>
Напишите прикованные <code>if</code> / <code>else if</code> выражения для выполнения следующих условий: <code>num &lt; 5</code> - return &quot;Tiny&quot; <br> <code>num &lt; 10</code> - возврат &quot;Small&quot; <br> <code>num &lt; 15</code> - возврат &quot;Средний&quot; <br> <code>num &lt; 20</code> - возврат &quot;Большой&quot; <br> <code>num &gt;= 20</code> - возврат &quot;Огромный&quot;

## Tests
<section id='tests'>
```yml
tests:
- text: You should have at least four <code>else</code> statements
testString: assert(code.match(/else/g).length > 3);
- text: You should have at least four <code>if</code> statements
testString: assert(code.match(/if/g).length > 3);
- text: You should have at least one <code>return</code> statement
testString: assert(code.match(/return/g).length >= 1);
- text: <code>testSize(0)</code> should return "Tiny"
testString: assert(testSize(0) === "Tiny");
- text: <code>testSize(4)</code> should return "Tiny"
testString: assert(testSize(4) === "Tiny");
- text: <code>testSize(5)</code> should return "Small"
testString: assert(testSize(5) === "Small");
- text: <code>testSize(8)</code> should return "Small"
testString: assert(testSize(8) === "Small");
- text: <code>testSize(10)</code> should return "Medium"
testString: assert(testSize(10) === "Medium");
- text: <code>testSize(14)</code> should return "Medium"
testString: assert(testSize(14) === "Medium");
- text: <code>testSize(15)</code> should return "Large"
testString: assert(testSize(15) === "Large");
- text: <code>testSize(17)</code> should return "Large"
testString: assert(testSize(17) === "Large");
- text: <code>testSize(20)</code> should return "Huge"
testString: assert(testSize(20) === "Huge");
- text: <code>testSize(25)</code> should return "Huge"
testString: assert(testSize(25) === "Huge");
```

## Challenge Seed
<section id='challengeSeed'>
<div id='js-seed'>
```js
function testSize(num) {
// Only change code below this line
return "Change Me";
// Only change code above this line
}
// Change this value to test
testSize(7);
```
</div>
</section>
## Solution
<section id='solution'>
```js
function testSize(num) {
if (num < 5) {
return "Tiny";
} else if (num < 10) {
return "Small";
} else if (num < 15) {
return "Medium";
} else if (num < 20) {
return "Large";
} else {
return "Huge";
}
}
