Typescript - a necessity front-end tool
summary
Claim: Typescript cuts unit-test surface by about 10–20% by catching nullability and type mismatches earlier. Practical steps include installing and running tsc, using tsc --watch, creating tsconfig with strictNullChecks, compiling test.ts to test.js, and adding @types (example @types/react) or custom .d.ts files. Demos show VS Code intellisense improvement, union types and interfaces for props, and successful compilation and incremental builds that prevent many integration regressions.
