Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

const messages = [
'Visualize',
'your',
'own',
'code',
'here!',
];
// highlight each line of messages recursively
function highlight(line) {
if (line >= messages.length) return;
const message = messages[line];
// visualize {
logTracer.println(message);
array2dTracer.selectRow(line, 0, message.length - 1);
Tracer.delay();
array2dTracer.deselectRow(line, 0, message.length - 1);
// }
highlight(line + 1);
}
(function main() {
// visualize {
Layout.setRoot(new VerticalLayout([array2dTracer, logTracer]));
array2dTracer.set(messages);
Tracer.delay();
// }
