What they are & how & when to use them
React Refs allow us to reference a DOM element or a class component from within a parent component. This gives us the ability to modify or change that element.
Think of refs as a direct connection between components and DOM elements or class components and their parent components. This connection provides us with the means to access elements/components without state updates and rerenders. I can think of a few useful ways that refs can be beneficial and we will explore some of those throughout this blog. I will mention that…
Hooks are a buzz in React right now, but what exactly are they, and why are they beneficial to us?
Hooks are a new addition in React 16.8. They let you use state and other React features without writing a class.
That’s pretty powerful stuff. We used to be confined to class components whenever we needed to use
componentDidMount anywhere in our applications. React Hooks eliminate the need for class components. Let’s think critically about why this could be important? Have you ever written out a beautiful functional component that has a load of branching logic and realize…
n-Notation & Big O
In computer science, we need a way to be able to compare algorithms to each other. Comparison allows us to see which algorithm is more efficient and we love efficiency. Run times of different programs are usually written in n-Notation. So if we want to look up how fast a certain algorithm is, we will need to know this notation to be able to understand it. But what exactly is it?
n-Notation is represented as a function of n. All this means is that the program is going to be related to that variable “n” in…
Hi everyone, this is part two in a series of blogs I am doing on Sass. If you haven’t read the first one and need help getting started with Sass please feel free to read my first blog, here. In this blog, I will be covering class naming conventions using the BEM, nesting in Sass, and Sass Variables.
The BEM is a methodology aimed at decreasing the footprint left by CSS. That is, CSS code can get really unorganized and hard to read. The BEM is a way that structures your naming conventions to increase readability and functionality. This is…
Let’s look at a real-world example, let’s say you have an application that allows you to view your blogs, your profile page, and your drafts. Each of those pages is a different view of the same SPA (single page application)…
General Overview, Installation & Setup
I plan to do a series of blogs each week on setting up Sass in your next project. Sass is an awesome tool that compiles all of your CSS for you. It’s really quite magical and allows you to create variables and other goodies so you can keep your code DRY. Huge plus. It is also a great way to keep things organized so you can easily find code and make changes whenever necessary. Sass is “CSS with superpowers” after all.
CSS gets very messy, very quickly. Having a single CSS file with thousands of…
React’s state is data that is changed inside your components. That is, you set a default value and you can change it depending on which component you send the information to or what you decide to do with it. …
let newVariable = 'I am an initialized variable now';
Declared variables (variables with values not yet initialized) are defaulted to
