Storing data into variables | Node-RED Essentials | Tutorial

Working with contexts, flow and global variables in Node-RED is a valuable skill when building complex automations.
Using JSON and JavaScript makes it a fairly intuitive experience in Node-RED.
I show you examples using the Change Node and the Function Node; these are both very useful nodes.
Check out my video on the Function Node: • Node-RED Function Node...

Thank you. Very helpful

For the saving variables across node-red restarts section: how do I find the settings.js.
I legit installed Studio Code but there is no folder node red

The default folder has since changed to the Node Red folder within the new 'addon_config' folder. The latter is not visible by default.
To access the .js file, I installed the File editor add-on. By disabling 'Enforce Basepath' in its 'Configuration ' tab, you gain access to 'addon_config'. This alllows you to see the Node Red folder and the .js file you're looking for.
