Module: Function

// to understand common workarounds for this limitation of ES6 modules.

/*~ If this module is a UMD module that exposes a global variable ‘myFuncLib’ when *~ loaded outside a module loader environment, declare that global here. *~ Otherwise, delete this declaration. */ exportasnamespacemyFuncLib;

/*~ If you want to expose types from your module as well, you can *~ place them in this block. Often you will want to describe the *~ shape of the return type of the function; that type should *~ be declared in here, as this example shows. *~ *~ Note that if you decide to include this namespace, the module can be *~ incorrectly imported as a namespace object, unless *~ –esModuleInterop is turned on: *~ import * as x from ‘[~THE MODULE~]’; // WRONG! DO NOT DO THIS! */ declarenamespaceGreeter { exportinterfaceLengthReturnType { width: number; height: number; } exportinterfaceNamedReturnType { firstName: string; lastName: string; }
