Looking for a JavaScript code that can animate vertical black bars of a specific width moving over a white background. The desired outcome is similar to the video found at: https://www.youtube.com/watch?v=bdMWbfTMOMM. Thank you.

For creating animations, I find <canvas> to be the best option. It's very user-friendly especially if you have a good grasp on JavaScript.
If you're familiar with <canvas> and its usage in conjunction with JS, here's a simple example to kickstart your understanding:
var $c = $('.canvas');
var ctx = $c[0].getContext('2d');
var x = [0, 40, 80, 120, 160, 200, 240, 280, 320, 360, 400];
setInterval(() => {
ctx.clearRect(0, 0, 400, 200);
var out = x.indexOf(401);
if (out !== -1) {
x[out] = -40;
}
ctx.fillStyle = 'black';
for (var i = 0; i < x.length; i++) {
ctx.fillRect(x[i], 0, 20, 200);
x[i]++;
}
}, 20);.canvas {
background-color: #fff;
border: 1px solid black;

<canvas class='canvas' width='400px' height='200px'>Eeek canvas not supported</canvas>This code is straightforward. If you understand the basics of <canvas>, this should be easy to comprehend.
