Quick Reference
The do…while statement defines a code block to be executed at least once, and repeated as long as a condition is true.
<!-- html element to place output -->
<p id="my_output"></p>
The following loop will run until i = 5, outputting the numbers represented by i to the page. Notice that since it runs the code first, and then checks for the condition, it will run at least once even if it started as 5 or more.
// variable
let text = '';
let i = 0;
// loop
do {
text += i + '<br>';
i++;
}
while (i < 5);
// output to HTML element
document.getElementById('my_output').innerHTML = text;
Output
0
1

Syntax

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.

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)
