Protection against DOM change via console?

Question

HTML

Interested in the issue of tracking the substitution of values ​​in HTML forms.
For example, in complex calculators for calculating the cost of services, where it is rather problematic to filter and predict all the actions of a coolhacker. I would like to just drop binds on forms when trying to correct values ​​in hidden inputs or data attributes.
It is clear that the recalculation and reconciliation with the values ​​from the database takes place on the server, but it is still more logical to confine ourselves to reconciliation on the client.
Perhaps there is a ready-made library. Couldn't come up with anything sensible.

Answer 1

It's more logical just to check everything on the server. The request can be issued and bypassing the browser.
