## Description
|
|
<section id='description'>
|
|
If you have multiple conditions that need to be addressed, you can chain <code>if</code> statements together with <code>else if</code> statements.
|
|
|
|
```js
|
|
if (num > 15) {
|
|
return "Bigger than 15";
|
|
} else if (num < 5) {
|
|
return "Smaller than 5";
|
|
} else {
|
|
return "Between 5 and 15";
|
|
}
|
|
```
|
|
|
|

|
|
|
|

|
|

|
```yml
|
|
tests:
|
|
- text: You should have at least two <code>else</code> statements
|
|
testString: assert(code.match(/else/g).length > 1, 'You should have at least two <code>else</code> statements');
|
|
- text: You should have at least two <code>if</code> statements
|
|
testString: assert(code.match(/if/g).length > 1, 'You should have at least two <code>if</code> statements');
|
|
- text: You should have closing and opening curly braces for each condition
|
|
testString: assert(code.match(/if\s*\((.+)\)\s*\{[\s\S]+\}\s*else if\s*\((.+)\)\s*\{[\s\S]+\}\s*else\s*\{[\s\S]+\s*\}/), 'You should have closing and opening curly braces for each condition in your if else statement');
|
|
- text: <code>testElseIf(0)</code> should return "Smaller than 5"
|
|
testString: assert(testElseIf(0) === "Smaller than 5", '<code>testElseIf(0)</code> should return "Smaller than 5"');
|
|
- text: <code>testElseIf(5)</code> should return "Between 5 and 10"
|
|
testString: assert(testElseIf(5) === "Between 5 and 10", '<code>testElseIf(5)</code> should return "Between 5 and 10"');
|
|
- text: <code>testElseIf(7)</code> should return "Between 5 and 10"
|
|
testString: assert(testElseIf(7) === "Between 5 and 10", '<code>testElseIf(7)</code> should return "Between 5 and 10"');
|
|
- text: <code>testElseIf(10)</code> should return "Between 5 and 10"
|
|
testString: assert(testElseIf(10) === "Between 5 and 10", '<code>testElseIf(10)</code> should return "Between 5 and 10"');
|
|
- text: <code>testElseIf(12)</code> should return "Greater than 10"
|
|
testString: assert(testElseIf(12) === "Greater than 10", '<code>testElseIf(12)</code> should return "Greater than 10"');
