The fy suffix in js - where did it come from?

Question

IT terminology

Where did the js fashion for the suffix (I hope I use the term for this part of the word correctly) "fy" come from? - jsonify, browserify, connectify, etc.

It has some special importance in the js ecosystem, maybe some kind of convention or is it just for fun that many people call libraries, functions, modules, etc.?

in short: the suffix -fy in English means "to make/give a property". For example, simple - simplify (simple - simplify, make simple), electric - electrify (electric - electrify, endow with electricity) and so on. This is not a feature of the JavaScript language specifically.
Therefore, jsonify means "endow json property", otherwise "cast to json format".
