Quick Reference
The Array reverse() method reverses the order of the items in an array, overwriting the original array.
<!-- html element to place output -->
<p id="my_cars"></p>// array
let cars = ['Lamborghini', 'Ferrari', 'Maserati', 'Alfa Romeo'];
// output the reversed array to the HTML element
document.getElementById('my_cars').innerHTML = cars.reverse();Note
Arrays count starting from zero NOT one. So item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on.
Output
Alfa Romeo,Maserati,Ferrari,LamborghiniSyntax
array.reverse()JavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
