“You don’t know what you don’t know”
I found out about some stuff I did not know I didn’t know this week, and was pretty appalled at this gap in my basic knowledge. I started researching furiously and will share my key takeaways. (I’ll assume you have a basic understanding of HTML in general.)
The word “semantic” means:
relating to meaning in language or logic
So Semantic HTML is the concept of writing markup that actually has meaning, as opposed to being used solely for creating a specific look or design. Here’s an example to demonstrate what I mean:
You want to use TypeScript in React but you’re not sure how to start. You’ve come to the right place! (We won’t be talking about TS syntax this time around — just getting up and running.)
If you’re building a new app and using create-react-app, the Create React App docs are great:
You can start a new TypeScript app using templates. To use our provided TypeScript template, append
--template typescriptto the creation command.
npx create-react-app my-app --template typescript
It compiles beautifully with no special settings to enable or packages to download. All the files that would have been
Ahhh, scope and closures: 2 favorite tech interview questions that trip up devs of all ages!
Scope is access. That’s the easiest way to think about it. It allows you, as a developer, to limit access to certain variables to specific contexts. It has two benefits:
let i = 0in separate
forloops in the same function 🙋♀️)
I’d encountered recursion in passing through casual discussions, mentioned in articles, etc. It seemed like the big bad wolf of programming. A function that calls itself? Confusing! I knew I’d tackle understanding it eventually, and that fine day finally arrived this week.
I’m currently working through Colt Steele’s Udemy course on Data Structures and Algorithms (couldn’t recommend it more highly) and Recursion is one of the first topics. He broke it down in a way that cleared away the cobwebs of confusion and made it extremely manageable to understand.
There are a few key pieces to recursion that you need…
If you’re in the software world, you’ve heard of stacks. Stackoverflow, anyone? If you’ve always wondered what that actually means, you’re in the right place.
I happen to be intimately familiar with pancake stacks, which is the first thing that comes to mind when I hear the word “stack.” Luckily, it is a fitting visual description for a software stack.
It is a data type similar to an array that behaves as a collection of elements. In this visual example, each pancake represents some element, which has been added to the top of the stack, and can also only be…
In theory, callback functions are very straightforward if you have some basic knowledge of writing code. …
You’re new to web development, and you want to build a web app. You might start with Ruby on Rails, which is an established framework for building websites. Technically, it’s a software library of a LOT of Ruby code that others have written — making it a gem! See my post on gems to learn more about neatly packaged Ruby code.
When getting a good sense of how Rails works, I think it helps to understand the basics of the big picture, so let’s back up a level and talk about how the web works. And I do mean web…
If you’re learning Ruby, you have definitely heard of (and have probably unknowingly used) Ruby gems. If they are as much a mystery to you as they were to me about a week ago (which is to say, the word “gem” only conjures up the image of a glimmering stone and has nothing to do with coding), come along for the ride as we explore them together.
For starters, open your terminal and type:
Can it be?? That is a very long list of gems that (if you’re anything like me) you didn’t even know…
