 Performs left-to-right function composition for asynchronous functions.
 
-Use `Array.prototype.reduce()` with the spread operator (`...`) to perform left-to-right function composition using `Promise.then()`.
-The functions can return a combination of: simple values, `Promise`'s, or they can be defined as `async` ones returning through `await`.
-All functions must be unary.
+Use `Array.prototype.reduce()` and the spread operator (`...`) to perform function composition using `Promise.then()`.
+The functions can return a combination of normal values, `Promise`s or be `async`, returning through `await`.
+All functions must accept a single argument.

 const pipeAsyncFunctions = (...fns) => arg => fns.reduce((p, f) => p.then(f), Promise.resolve(arg));
