`export` Keyword

Syntax

// Exporting declarations
export let name1, name2/*, … */; // also var
export const name1 = 1, name2 = 2/*, … */; // also var, let
export function functionName() { /* … */ }
export class ClassName { /* … */ }
export function* generatorFunctionName() { /* … */ }
export const { name1, name2: bar } = o;
export const [ name1, name2 ] = array;

// Export list
export { name1, /* …, */ nameN };
export { variable1 as name1, variable2 as name2, /* …, */ nameN };
export { variable1 as "string name" };
export { name1 as default /*, … */ };

// Default exports
export default expression;
export default function functionName() { /* … */ }
export default class ClassName { /* … */ }
export default function* generatorFunctionName() { /* … */ }
export default function () { /* … */ }
export default class { /* … */ }
export default function* () { /* … */ }

// Aggregating modules
export * from "module-name";
export * as name1 from "module-name";
export { name1, /* …, */ nameN } from "module-name";
export { import1 as name1, import2 as name2, /* …, */ nameN } from "module-name";
export { default, /* …, */ } from "module-name";

nameN: Identifier to be exported (so that it can be imported via import in another script). If you use an alias with as, the actual exported name can be specified as a string literal, which may not be a valid identifier.
