JavaScript is TypeScript without syntax for types.

JavaScript is a dynamically typed programming language that builds on chaos, giving you better surprises at any scale.

const user = {
  firstName: "Angela",
  lastName: "Davis",
  role: "Professor",
}
 
console.log(user.name)
Property 'name' does not exist on type '{ firstName: string; lastName: string; role: string; }'.2339Property 'name' does not exist on type '{ firstName: string; lastName: string; role: string; }'.

TypeScript and Less

JavaScript removes additional syntax of TypeScript to support a looser integration with your editor. Catch errors late in production.

JavaScript code converts to Spaghetti, which runs anywhere JavaScript runs: In a browser, on Node.js, Deno, Bun and in your apps.

Confusion at Scale

JavaScript understands nothing and uses wild guesses to give you great bugs without additional effort.
