No, It is very important to reduce programmatic and stylistic code errors by finding and fixing them early and also improving code quality.

Describe the solution you'd like

Introduce eslint unicorn to enforce:

• kabab-case file naming structure
• error exception on empty files

Introduce prettier to format files gracefully

• add .prettierrc file and define styling rules
• extend the rules to eslint configuration file

This approach will help contributors improve overall code quality as well as reduce programmatic and stylistic errors.
