Troubleshooting

When running a script after another, sometimes, the browser does not reload and does not display the wanted execution. Here are some solutions :

1. Do not forget to run the build script before running the execution
2. Remove .parcel-cache and dist folders (generated by npm run)
3. Clear the browser cache. On firefox just press Ctrl + Shift + R, it will reload the webpage and clears the cache
