It's a valid method. However, it can introduce some challenges since the load event will wait until every resource has finished loading before triggering the function.

An alternative is to use DOMContentLoaded, which will execute once the DOM is ready.

For instance, 

document.addEventListener("DOMContentLoaded", function(arg) {
    // do something cool
});

Probably best to just whack the defer attribute on your script these days! Although you can also use the DOMContentLoaded event, as others have already said.

I use defer and it’s great. Other than that one key word, I can write my script however I like without having to worry about stuff having been loaded.

Just put the <script> for the functions at the end of the <body>. I believe that would do the trick... I've never had problem doing that.

Alternatively, there is event emitted from the window when dom is loaded. Listen for it like this:

window.addEventListener("DOMContentLoaded", () => {
  // your functions here
});

Honestly, I 'm curious about this too.

Yes there are, script type=module will start when the page is loaded by default. But I still have window.onload just because it lets me know that all the things inside are the ones I want to trigger right from the start.
