// Exporting individual features
export let name1, name2,, nameN; // also var, const
export let name1 =, name2 =,, nameN; // also var, const
export function functionName(){...}
export class ClassName {...}

// Export list
export { name1, name2,, nameN };

// Renaming exports
export { variable1 as name1, variable2 as name2,, nameN };

// Exporting destructured assignments with renaming
export const { name1, name2: bar } = o;

// Default exports
export default expression;
export default function () {} // also class, function*
export default function name1() {} // also class, function*
export { name1 as default,};

// Aggregating modules
export * from; // does not set the default export
export * as name1 from; // Draft ECMAScript® 2O21
export { name1, name2,, nameN } from;
export { import1 as name1, import2 as name2,, nameN } from;
export { default } from;

Example 3: javascript export default

export default const array = [1, 2, 3];
export default let array = [1, 2, 3];
export default var array = [1, 2, 3];
export default const variable = 'value';
export default let variable = 'value';
export default var variable = 'value';
export default const variable;
export default let variable;
export default var variable;
export default function functionName () {
  // ...
}
export default class ClassName {
  // ...
}
// Before you use export default: You can't have 2 or more export default's.
