INSIGHT

Why TypeScript Won In 2025

TypeScript became GitHub's most used language driven by frameworks scaffolding TypeScript by default and AI-assisted development.
Hosts argue types provide context that improves both human and LLM-generated code quality.

ADVICE

Use LLMs With TypeScript For Migrations

Try using LLMs with TypeScript for migrations and code generation because types reduce ambiguity and reveal errors earlier.
Kamran reports a Copilot prompt fully migrated an MCP server to Azure Functions without manual edits.

INSIGHT

Type-Safe Regular Expressions

ArkRegex (ArcRegex) provides type-only, compile-time typed regular expressions that evaporate at runtime.
It yields typed tuples and named capture types so editor tooling catches mismatched groups early.
