JavaScript/TypeScript

JavaScript is the engine of the web, and TypeScript is its industrial-grade safety suit.

JavaScript powers 98% of the world's websites, but its dynamic nature can lead to runtime errors in complex builds. TypeScript solves this by adding a static type system on top of JavaScript (ECMAScript 2023 standards). It catches bugs during development, enables precise IDE autocompletion, and compiles down to clean JS that runs anywhere from a Chrome browser to a Node.js server. By using interfaces and generics, teams at companies like Microsoft and Airbnb manage millions of lines of code with fewer regressions.
