As part of the migration towards modern web standards and the adoption of Vue 3 we can replace most calls to jquery methods by native ES6 features.

List of possible replacements:

• $.Deferred(): new Promise()
• $.when() : Promise.all()
• $.isEmptyObject(obj) : Object.keys(obj).length === 0; (Note this fails for dates, not relevant in our case I think)
• $.getJSON(): fetch()
