Chapter XXII · Modules
export
The `export` statement makes functions, objects, or primitive values available to other modules for importing.
01 How It Works
Think of placing finished tools on a public display shelf for other workers to borrow.
Values can be exported either as named exports or as a single default export per module file.
example.js
export const API_KEY = "12345";
export function calculate() { return 100; }1. Prefix declarations with the `export` keyword.
2. Alternatively, use `export default` for primary module values.
3. Make code public to other importer modules.
02 Practical Example
Here is how you might see this concept applied in real-world code:
practical.js
export default class UserProfile {
constructor(name) { this.name = name; }
}Key Takeaway
Use `export` to expose module functionality safely to other parts of your application.
