      The Latest Videos

      🆕020. Destructoring - 09:00 [javascript]

      Very quick intro into one of the coolest features of JavaScript. We'll learn how to use destructoring with arrays, objects and strings. Plus how to make any object "destructible" (spoiler: just make it iterable).


      🆕019. Building a REST API with Koa (Part 2) - 19:06 [node, koa]

      In the second part we are connecting a database (Knex.js + PostgreSQL) and modifying the router a little bit more. We create the migrations, the seed and run some very simple queries in order to use them in our API.

      -> Source Code Of The Project


      🆕018. Building a REST API with Koa (Part 1)  - 18:00 [node, koa]

      In the first part we are going to get a closer look at Koa which is server-side framework for Node with a minimal API with support for async/await syntax. It is based on using the middle-wares which are just simple functions that can be stacked together in a chain. Every middleware does its job and then passes the state to the next one.


      017. OOP In JavaScript: The Prototype Chain - 11:46 [language]

      The object model implemented in JavaScript is significantly different from other mainstream object-oriented languages like Java or C++. Even thought the syntax is very similar, especially with the class declaration introduced in 2015 with ECMAScript 6, the structural difference is huge. In this video, we'll see how the prototype chain (which is a very basis for OOP in JavaScript) works.


      016. Optimizing Performance With React Hooks - 12:16 [react]
