This is just an empty function.
This can be used, instead of manually creating empty functions which bloats the source-code.
It’s analogous to jQuery’s $.noop()
function.
Example:
const ExamplePluginFunction(opts) {
opts = opts || {};
// Use the passed callback function or an empty one.
opts.callback = opts.callback || TOnlineMediaplayerFramework.Noop;
const a = document.createElement("a");
a.innerHTML = "Demo Testlink";
a.addEventListener("click", opts.callback);
document.body.appendChild(a);
}
