First of all this is my 1st stackoverflow post so sorry if I am missing context or do if the question is too out of the ordinary.. Onto some context and example use case for my question.
Context I'm making a simple app for an uni assignment in React-Native but one of the requirements client we are making it for is that the text (copy) in the app can be adjusted by him after we deliver it to him.
Example Use Case They want to change the text on the welcome screen from "Welcome, [Name]" to "Hello there, [Name]". But they aren't technical so they expect to be able to change this in a simple UI.
I've tried googling for solutions but keep finding Localization solutions instead and all I've found so far require in-code edits.
