These unique names are called identifiers. log ( obj . JavaScript Objects can be converted into JSON, and JSON can be converted back into JavaScript Objects. And call a function that loads the json object with the variables from the file from which you can extract the variable by its key something in this direction perhaps: Tip: To check if a JavaScript file is part of JavaScript project, just open the file in VS Code and run the JavaScript: Go to Project Configuration command.
