linter to take into account node.js

[TanyaStere42]

Feature description and context

We're using node.js but our linter does not recognize it, requiring manual adjustments to avoid errors being thrown. We want to adjust configuration so node.js is recognized and processing is handled automatically.

Feature sign-off requirements

• node.js: true for eslinter
• removal of all inline comments that were used for manual adjustments
  • this line used before process.env // eslint-disable-next-line no-undef
  • this line at the top of files /* eslint-disable no-undef */
• resolve any undefined references that were missed through manual adjustments
