About TypeScript

TypeScript is a strongly typed programming language that builds on JavaScript, giving you better tooling at any scale.

It adds optional static typing, classes, interfaces, and other features that help catch errors early and improve code maintainability.

Formatting Options

  • Tab Width: Number of spaces per indentation level
  • Semicolons: Add semicolons at end of statements
  • Single Quotes: Use single quotes instead of double
  • Trailing Comma: Add trailing commas in multi-line
