What is TypeScript? — UK Software Development Guide
Direct Answer
TypeScript is a programming language developed by Microsoft that adds static type definitions to JavaScript. TypeScript code is compiled (transpiled) to standard JavaScript before it runs in a browser or Node.js. The type system catches many errors at compile time that would otherwise only appear at runtime, making large codebases more maintainable.
Typescript in the UK
TypeScript has become the default choice for new UK software projects using JavaScript frameworks — replacing plain JavaScript for most enterprise and startup work. ClickMasters uses TypeScript for all React frontends and Node.js backends by default. The UK developer talent pool strongly prefers TypeScript over JavaScript for new projects: it's considered essential for senior roles and its adoption has grown rapidly since 2020. TypeScript's type safety aligns with UK GDPR accountability requirements — type-safe data models reduce the risk of accidental personal data exposure.
