## Description
|
||
|
|
<section id='description'>
|
||
|
|
Order is important in <code>if</code>, <code>else if</code> statements.
|
||
|
|
The function is executed from top to bottom so you will want to be careful of what statement comes first.
|
||
|
|
Take these two functions as an example.
|
||
|
|
Here's the first:
|
||
|
|
<blockquote>function foo(x) {<br> if (x < 1) {<br> return "Less than one";<br> } else if (x < 2) {<br> return "Less than two";<br> } else {<br> return "Greater than or equal to two";<br> }<br>}</blockquote>
|
||
|
|
And the second just switches the order of the statements:
|
||
|
|
<blockquote>function bar(x) {<br> if (x < 2) {<br> return "Less than two";<br> } else if (x < 1) {<br> return "Less than one";<br> } else {<br> return "Greater than or equal to two";<br> }<br>}</blockquote>
|
||
|
|
While these two functions look nearly identical if we pass a number to both we get different outputs.
|
||
|
|
<blockquote>foo(0) // "Less than one"<br>bar(0) // "Less than two"</blockquote>
|

## Instructions
|
||
|
|
<section id='instructions'>
|
||
|
|
Change the order of logic in the function so that it will return the correct statements in all cases.

|
```yml
|
||
|
|
- text: <code>orderMyLogic(4)</code> should return "Less than 5"
|
||
|
|
testString: 'assert(orderMyLogic(4) === "Less than 5", "<code>orderMyLogic(4)</code> should return "Less than 5"");'
|
||
|
|
- text: <code>orderMyLogic(6)</code> should return "Less than 10"
|
||
|
|
testString: 'assert(orderMyLogic(6) === "Less than 10", "<code>orderMyLogic(6)</code> should return "Less than 10"");'
|
||
|
|
- text: <code>orderMyLogic(11)</code> should return "Greater than or equal to 10"
|
||
|
|
testString: 'assert(orderMyLogic(11) === "Greater than or equal to 10", "<code>orderMyLogic(11)</code> should return "Greater than or equal to 10"");'
