TypeScript vs. JSDoc JavaScript for static type checking

The discussion around choosing between JavaScript and TypeScript for projects often centers on the benefits of static typing, which is a key strength of TypeScript. While historically JavaScript lacked this feature, advancements in JSDoc annotations now allow JavaScript to be type-checked, offering a middle ground for developers who prefer not to engage in a compilation step. This approach has been exemplified by large projects like webpack, which adopted JSDoc for type checking without converting to TypeScript. Though JSDoc enhances JavaScript with type safety, TypeScript remains favored for its better tooling support and more straightforward syntax. The choice between the two depends on project needs, with TypeScript recommended for larger projects due to its comprehensive static typing capabilities, while JSDoc is seen as a valuable tool for smaller projects or those with specific requirements against compilation. Both methods are viable, yet the preference often leans towards TypeScript for new projects to ensure ease of use and enhanced productivity.
