Writing a JavaScript project with TypeScript can provide several benefits, including type safety, improved tooling, and enhanced bug detection. To get started, you can configure your editor to use TypeScript to analyze your code, or enable TypeScript checking for all JavaScript files in your project. This can be done by adding a comment to the top of each file, enabling the "Check JS" setting in VS Code, or using tools like SonarLint and SonarQube. By introducing TypeScript into your project, you can take advantage of its type inference, highlight runtime bugs, and improve the reliability of your application. Additionally, you can fix missing types, add further types to make your JavaScript safer, and integrate TypeScript with other tools to gain more insight into how types flow around your application.
