How do I detect if an arrow key is pressed in JS? I am using HTML, and JavaScript canvas on a project and need to detect arrow keys pressed.

The arrow keys have key codes, so for example the left arrow key has the code 37, right arrow key code is 39, up is 38, and down is 40.
Then you could use switch cases to determine which key was pressed:
document.onkeydown = function (event) { // to get the key
switch (event.keyCode) {
case 37: // if it's the left arrow
console.log("Left key is pressed.");
break;
case 38: // if it's the up arrow
console.log("Up key is2 years ago
