Hooks are a new feature added to React as of version 16.8, and if you’re using React at all you probably already know how useful they’ve become. Whereas before, if you wanted to use state and certain other features, you needed to do so within a class-based component. With the introduction of hooks, users can now get access to state in a functional component through the useState hook. Let’s dive a little deeper into how it works and how to use it.
To understand the concept of promises in JavaScript, you’d need a little background on how JavaScript functions from the start. JavaScript is what’s known as “single-threaded”, meaning only one script can run at a time. To bypass this, you can make a function run only when something specific happens, like you would when adding an event listener. Doing this would hold the function script from execution until it’s specifically acted upon. This is essentially what makes up the foundation of a Promise in JavaScript!
One of the biggest benefits of working in Ruby/Rails is the access to Ruby gems. If you’ve been working in Ruby, you’ve undoubtedly already been working with at least a few gems to help you along, but what really IS a Ruby gem?
I’ll be honest, I don’t think I really had a great grasp on Sinatra routing, MVC, or forms all the way until working on my Sinatra portfolio project. Maybe it was the coronavirus-related turmoil enveloping everything, maybe it was trying to keep up with work, school, and a busy job hunt, maybe it was a turbid combination of all multiple factors, but nothing really clicked into place for me until I sat down and had to build it all out myself front to back. And that brought me to a realization, that’s relative to how I’ve always learned best.
