Single Line Comments
Any text between the // and the end of the line will be ignored by the browser (will not be executed). Anything on the line before the // will run normally. And anything on lines after the comment will run normally.
// this is a comment let x = 5; // this is also a comment let y = 8;
/* this is a a much longer comment let x = 5; */
The structure of the comment stays the same, but the comment itself is the code you no longer want the browser to run. In the following, we comment out the height of 40px and instead use window.innerHeight.
// variables let width = window.innerWidth; let height = /* 40px */ window.innerHeight; let x = document.getElementById('demo'); // write the URL to the HTML element x.innerHTML = 'Width: ' + width + '
Height: ' + height;
let height = /* 40 */ px window.innerHeight
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.
Thanks for your support!
