## Statements (checkable)
0. Netlify Docs (build troubleshooting tips): the Uncaught SyntaxError: Unexpected token error most commonly happens when the site code refers to an asset that is no longer available.  [✓0 ✗0]
1. For single-page apps that use code splitting or hashed file names, the page says filename changes from Netlify atomic deploys may break asset references on the site and result in this error.  [✓0 ✗0]

## Fix
```text
Reload the page (or the app) when a chunk fails to load after a deploy, and check that redirects/rewrites do not answer requests for missing JS assets with HTML.
```
