TypeScript 5.7 is now available for download through npm. The release candidate includes several improvements, including checking for never-initialized variables, path rewriting for relative paths, and a new compiler option called --rewriteRelativeImportExtensions. TypeScript has been able to catch issues when a variable has not yet been initialized in all prior branches, but it now reports errors when variables have never been initialized at all.
Path rewriting for relative paths is also introduced. TypeScript now supports running TypeScript code "in-place" without requiring a build step that generates output JavaScript files. However, this requires importing the appropriate TypeScript extension at runtime. To support this scenario, a new compiler option called --rewriteRelativeImportExtensions is added.
