Change JSON File with JavaScript

Question

Does changing a JSON file with JS acutally affect the JSON file or does it only change the JSON file in temp memory?

user.properties[0].firstName = "Jane";

Edit

I am not using a server to develop my website, but will be using one when I post it.

Unless you're writing the object back to disk it only affects the copy stored in memory — David

That would only affect the json in memory, you would then need to write the changes back to the filesystem for it to update the file contents.

How would I do that?

Post the changes back to the server and use whatever server side language you running to write the contents.

What if I am not using a server to design my website?

How are you hosting it then ? What is you dev setup?

I am hosting it on a local server.
