title: Introducing Else Statements
|
|
challengeType: 1

|
## Description
|
|
<section id='description'>
|
|
When a condition for an <code>if</code> statement is true, the block of code following it is executed. What about when that condition is false? Normally nothing would happen. With an <code>else</code> statement, an alternate block of code can be executed.
|
|
<blockquote>if (num > 10) {<br> return "Bigger than 10";<br>} else {<br> return "10 or Less";<br>}</blockquote>
|

|
|
## Instructions
|
|
<section id='instructions'>
|
|
Combine the <code>if</code> statements into a single <code>if/else</code> statement.

```yml

|
tests:
|
|
- text: You should only have one <code>if</code> statement in the editor
|
|
testString: assert(code.match(/if/g).length === 1, 'You should only have one <code>if</code> statement in the editor');
|
|
- text: You should use an <code>else</code> statement
|
|
testString: assert(/else/g.test(code), 'You should use an <code>else</code> statement');
|
|
- text: <code>testElse(4)</code> should return "5 or Smaller"
|
|
testString: assert(testElse(4) === "5 or Smaller", '<code>testElse(4)</code> should return "5 or Smaller"');
|
|
- text: <code>testElse(5)</code> should return "5 or Smaller"
|
|
testString: assert(testElse(5) === "5 or Smaller", '<code>testElse(5)</code> should return "5 or Smaller"');
|
|
- text: <code>testElse(6)</code> should return "Bigger than 5"
|
|
testString: assert(testElse(6) === "Bigger than 5", '<code>testElse(6)</code> should return "Bigger than 5"');
|
|
- text: <code>testElse(10)</code> should return "Bigger than 5"
|
|
testString: assert(testElse(10) === "Bigger than 5", '<code>testElse(10)</code> should return "Bigger than 5"');
|
|
- text: Do not change the code above or below the lines.
|
|
testString: assert(/var result = "";/.test(code) && /return result;/.test(code), 'Do not change the code above or below the lines.');
