No linting in a DB notebook available for now.

The Notebook is currently in the process of adopting Monaco as the underlying code editor which will offer an improved code authoring experience for notebook cells.

Some of the Monaco editor features enabled in the notebook include :

• Completions as you type
• Object inspection on mouse hover
• Code folding
• Multi-cursor support
• Column (box) selection
• Bracket-matching
• Side-by-side diffs in revision history
• Improved find-and-replace
• Better accessibility support

Need to wait for linting.
