Parsing JSON on the frontend?

Question

JavaScript

Does it make sense to get a field with the text {"a":1,"b":2,"c":3,"d":4,"e":5} (JSON) from the mysql database and return it as is. On the frontend in JS, parse and turn it into normal data to save CPU time?

Answer 1

It is more logical, of course, to transfer data to the client already in JSON with a certain structure and hierarchy. In all projects that I have seen, JSON data is already transmitted to the client.
But, if there is a problem with processor time, then you can entrust these operations to the client code. JavaScript is very good at parsing a string into JSON (JSON.parse).
