TypeScript
TypeScript is an enhanced version of JavaScript, which is one of the most popular programming languages for websites and apps. Think of it as JavaScript with extra features that help catch mistakes before they happen, making it easier to build and maintain large software projects. It's like having a spell-checker for code. Many big companies like Microsoft (who created it), Google, and Airbnb use TypeScript because it helps their development teams work more efficiently and make fewer errors. When you see TypeScript mentioned in a resume, it usually indicates that the candidate has experience with modern web development practices.
