Javascript won’t load or update in Odoo

If you are debugging JavaScript code in Odoo and it happens that you can’t get it updated or worst it’s not loading the official documentation is a good reference “What to do if a file is not loaded/updated”. But I experienced and issue as I always use –dev=all and the JavaScript won’t load at all sometimes. My solution was simply to remove –dev=all from the command line when staring Odoo ./start_odoo -d YOU_DATABASE_NAME –workers=0 -u YOUR_MODULE_NAME_THAT_CONTAINS_THE_JAVASCRIPT and than stop Odoo and start it again with the –dev=all this will refresh the assets.
