Just wondering, shouldn't we use
DOMContentLoadedinstead? My guess is that due to async loading we need to wait, but I'm thinking how we can improve this later.There was a problem hiding this comment.

Yes I was hesitating between both of them. IDK what's the best optimization.

The best optimization is to not block anything unless it's needed. So, in this case
DOMContentLoadedseems a better choice.Later, we could look into just building the Bootstrap parts we need and thus we probably won't need this code at all.
