console and Promise reported as not defined

[mvolkmann]

Describe the bug
When editing a .js file in src/lib, if I use console.log or Promise.all they work, but VS Code reports console and Promise as not defined.

To Reproduce
Steps to reproduce the behavior:

Create the file src/lib/demo.js containing the following:

console.log('demo');
const promises = [];
const p = Promise.all(promises);

Notice that console and Promise have squiggly red lines below them.

Expected behavior
VS Code should recognize these names as being defined.

The Svelte for VS Code extension does not provide any form of diagnostics to JS/TS files. What are the error messages / codes exactly? What is the project type where you are getting this error (SvelteKit, ESLint yes/no, etc)?

[mvolkmann]

Ah, sorry. The error is from ESLint. An example message is "'console' is not defined. eslint(no-undef)".
This is a SvelteKit project. Maybe I need to modify the .eslintrc.cjs file it provides.
Ah ha! The errors go away if I add this:

  env: {
    es6: true, // for Promise
    node: true // for console
  },

Perhaps these settings should be in .eslintrc.cjs by default for SvelteKit projects.
