Static Files Availability (old versions)

[tassioFront]

I have read the Static Web App doc but did not find information (maybe my fault) about the disponibility/availability of old static files.

Context/Case
Let’s say I have a current deployment version (which has a 0.0.1.js file) and then I deploy a new version (which has a 0.0.2.js file, but there is no 0.0.1.js file anymore). Will the 0.0.1.js file be available anyway?

Thinking even after deploying a new version, there will have users accessing my old site version and they might request files not existing anymore.

I'm asking because of Unexpected token error.
