How do you assess the quality of your written code?

I verify compliance with technical specifications and design mockups. I use static code analyzers (ESLint, Stylelint) to enforce code style and identify potential errors. I write unit and integration tests using Jest and React Testing Library. I evaluate performance: load time, script execution speed, and absence of "lags" on various devices. I perform manual testing of functionality and responsiveness across different browsers and devices. I receive feedback from colleagues during code review.

// Example of ESLint usage in package.json
"scripts": {
  "lint": "eslint . --ext .js,.jsx,.ts,.tsx",
  "test": "jest"
}
