ES Module Syntax: import and export

Use named and default exports in TypeScript files.

Welcome

TypeScript supports ES module syntax for organizing code into separate files. This lesson covers named exports, default exports, and imports.

Use `export` to make a declaration available to other files.

// math.ts
export function add(a: number, b: number): number { return a + b; }
export const PI = 3.14159;
export interface Config { host: string; }
