Avoid Synchronous Functions in Node.js
Sync Functions can dramatically slow down your app and they are almost never necessary.

Implementing "Options Object" Pattern using TypeScript and Joi
The Options Object pattern [1][2] is a technique in JavaScript for configuring a component using a single function parameter:
