 Nest is a framework for building efficient, scalable <a href="https://nodejs.org" target="_blank">Node.js</a> server-side applications. It uses modern JavaScript, is built with <a href="https://www.typescriptlang.org" target="_blank">TypeScript</a> (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).
 
-<p>Under the hood, Nest makes use of <a href="https://expressjs.com/" target="_blank">Express</a>, but also, provides compatibility with a wide range of other libraries, like e.g. <a href="https://github.com/fastify/fastify" target="_blank">Fastify</a>, allowing for easy use of the myriad third-party plugins which are available.</p>
