General Custom Code Question

Hello all,

Can someone explain to me - what are the limitations of custom code? I am not a coder… but If I build an ecommerce website in Webflow… and paid an expert in jquery or react or node or angular are there any limitations to what can be done via webflow?

For example if there was some functionality that wasn’t available in Webflow (I want to implement a date & time delivery slot scheduler for the customer for example).

What about if I exported the html and CSS and had a developer work on it outside of Webflow is that possible?

Basically what I’m asking are there any limitations if I paid someone to develop the code? Or is there only so much you can do injecting scripts into webflow via head/body…?
