There's this, but they don't tell you where it goes: Splash—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers
And there's nothing on ArcGIS API for JavaScript 4.8 sample code page: Samples Overview | ArcGIS API for JavaScript 4.8
Jared,
Here is a sample of a Splash Screen that goes away after a few seconds:

Nice, Robert Scheitlin, GISP
One question...what's the Dialog argument on line 84?
Good enough, thanks!
Robert,
Sorry, I should have mentioned I'm building a custom app. Ok, so the code in WAB page won't work. I'm looking for a way to display a small paragraph about the app when the user first opens the page. I thought a splash screen could work nicely.
I also tried a window alert, but I don't like the look: Tryit Editor v3.5
In this question on Geonet someone asks a similar question, but the answers refer to outside sources:
https://community.esri.com/thread/202969-splash-screen-with-the-arcgis-js-api-4x
Is there not a way using ArcGIS for JS?
You have a link to the Web App Builder Splash widget there and then you start talking about the 4.x JS API. These are two very separate things. The Splash widget is for use in a WAB application NOT a custom JS API app.
