Ginni Rometty, the CEO of IBM once said, “Growth and comfort do not coexist.” As software developers, learning a new language or a new skill is necessary to grow and get us out of our comfort zones. This week at Hacker Noon, we’ve seen some great tutorials that will help you do just that!

JavaScript:

Promises in 70 lines of code

Ever wondered how JavaScript Promise works internally? Obviously there is some native browser support involved, right? Nope! We can implement the Promise interface using pure JavaScript and it’s much simpler than you may think, we can do so in only 70 lines of code!

Build a machine learning website from scratch

Are you enthusiastic about machine learning? Are you trying to implement a simple machine learning webpage from scratch? Do you want to make something cool with HTML/CSS and JavaScript? If yes, then this tutorial is for you!

Build a currency converter with JavaScript and Ionic

Are you comfortable building web applications with JavaScript, but want to try something new? Have you wanted to learn about mobile app development, but never made the time to do so? This tutorial uses Ionic, which relies heavily on all the great features of JavaScript, to build a really cool currency converter.

Monolith to micro frontends

Do you dread resolving merge conflicts? Do you work on large development teams where tasks can sometimes overlap or cause confusion? This guide explains how microservices can help. Microservice is a development technique which allows developers to do independent deployments for different parts of the platform without harming other parts

Node:

Build a twitter bot on AWS lambda

Do you want some hands on experience with a seemingly complex tool used widely in the industry? Or do you just want a fun side project? This tutorial gives step by step instructions on how to build a twitter bot on AWS lambda and provides a cool use-case for Webpack! You’ll walk away with some new skills and a great portfolio piece.

React:

Build a customized youtube player

Don’t have time to go through long tutorials? Need an easy way to finally break into React? In this tutorial, you’ll learn how to connect to the youtube API with React, and build a customized Youtube player. The best part? You’ll be done in less than an hour!

Introduction to React hooks

Do you think classes can be a barrier to learning React? Or do you use classes, but find that they make loading unreliable?
