If you wish to analyze the return type of a function without executing it, you can use the ts-morph library.

In an async function, the produced promise is resolved with the returned value.

Let's have a go at writing some functions featuring return values. Make a local copy of the function-library.html file from GitHub. This is a simple HTML page containing a text ltinputgt field and a paragraph. There's also a ltscriptgt element, in which we have stored a reference to both HTML elements in two variables. This page will allow you to enter a number into the text box, and display
