How to detect the presence of Scatter on page load?

[acoutts]

I can always check the window.scatter reference after a timeout, but is there a more reliable way to check if Scatter is installed?

[str]

document.addEventListener('scatterLoaded', scatterExtension => {
    const scatter = window.scatter;
    window.scatter = null;
    callYourCallback(scatter);
 });

I do that but won't that CB only execute if the scatterLoaded event fires?

What I'm looking for is a way to detect when that doesn't work, perhaps the timeout I'm using is the best option but I wanted to see what else was available.

Yup, only a timeout. Scatter can't tell you that it doesn't exist.
