## Description
|
||
|
|
<section id='description'>
|
||
|
|
In the previous challenge, you used a single <code>conditional operator</code>. You can also chain them together to check for multiple conditions.
|
||
|
|
The following function uses if, else if, and else statements to check multiple conditions:
|
||
|
|
<blockquote>function findGreaterOrEqual(a, b) {<br> if(a === b) {<br> return "a and b are equal";<br> }<br> else if(a > b) {<br> return "a is greater";<br> }<br> else {<br> return "b is greater";<br> }<br>}</blockquote>
|
||
|
|
The above function can be re-written using multiple <code>conditional operators</code>:
|
||
|
|
<blockquote>function findGreaterOrEqual(a, b) {<br> return (a === b) ? "a and b are equal" : (a > b) ? "a is greater" : "b is greater";<br>}</blockquote>
