Quick Reference
The Array sort() method sorts the elements of an array as strings in alphabetical and ascending order, overwriting the original array.
<!-- html element to place output -->
<p id="my_cars"></p>// array
let cars = ['Lamborghini', 'Ferrari', 'Maserati', 'Alfa Romeo'];
// sort array
cars.sort();
// output the sorted array items to the HTML element
document.getElementById('my_cars').innerHTML = cars;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,Ferrari,Lamborghini,MaseratiSyntax

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.
