Windows 10 Javascript Data Structure and Data Editor

I have an application where I want to build a complex data structure which is local to the application… hence I want to create the data structure and the data that goes with it in a javascript file.

Can anyone recommend a javascript editor running under Windows 10 that will allow me to easily create and save such a data structure and the data too?

So I’m looking for something that works a bit like MySQL Workbench or phpmyadmin to create the js data structure and allow me to easily create and manage the data it stores.

In fact, can Wappler Database Manager do that?
