When it comes to long JavaScript tasks, how long is too long? The general consensus within the web performance community is that any JS scripting task that takes more than 50ms to execute can affect a user's experience. When the browser's main thread hits max CPU for more than 50ms, a user starts to notice that their clicks are delayed and that scrolling the page has become janky and unresponsive.
