TypeScript

TypeScript is a programming language that builds on JavaScript by adding type safety – essentially helping developers catch errors before they happen. It's widely used for web development, mobile apps, and enterprise software. For career changers, TypeScript skills open doors to front-end, back-end, and full-stack developer roles. Since many companies prefer TypeScript over plain JavaScript for larger projects, learning it gives you a competitive edge in the job market and demonstrates your commitment to writing reliable, maintainable code.
