The Thinking Behind Simplifying Event Handlers
9.5.2019
Events are used to respond when a user clicks somewhere, focuses on a link with their keyboard, and changes the text in a form. When I first started learning JavaScript, I wrote complicated event listeners. More recently, I've learned how to reduce both the amount of code I write and the number...

9.5.2019
If you’re familiar with popular JavaScript frontend frameworks like React, Angular, etc, then the concept of ECMAScript won’t be entirely new to you. ES Modules have the import and
A Few Functional Uses for Intersection Observer to Know When an Element is in View
8.5.2019
You might not know this, but JavaScript has stealthily accumulated quite a number of observers in recent times, and Intersection Observer is a part of that arsenal. Observers are objects that spot something in real-time — like birdwatchers going to their favorite place to sit and wait for the birds...
Getting To Know The MutationObserver API
8.5.2019
MutationObserver watches the DOM, specifically the places you tell it to, like:
document.querySelector('#watch-this');
...and it can tell you (trigger a callback) when stuff happens — like when a child is added, removed, changed, or a number of other things.
I used it just the other day...
Type Conversion with JavaScript Arrays
7.5.2019
JavaScript’s loose nature allows developers to employ amazing tricks to do just about anything you’d like. I’ve detailed how you can filter falsy values in arrays using a filter(Boolean) trick, but reader David Hibshman shared another trick for typecasting array values the same...
Split
2.5.2019
Jeremy on the divide between the core languages of the web, and all the tooling that exists to produce code in those languages:
On the one hand, you’ve got the raw materials of the web: HTML, CSS, and JavaScript. This is what users will ultimately interact with.
On the other hand, you’ve got...
Flow Object.values(…)
2.5.2019
JavaScript typing utilities, like Flow and TypeScript, have become popular in JavaScript apps of all sizes. As I mentioned in our Script & Style Show typing podcast, typing is a great way to implicitly implement documentation and validation. Flow isn’t always easy to perfect, however,...
The Many Ways of Getting Data Into Charts
1.5.2019
Data is available everywhere nowadays, whether it’s in a plain text file, a REST API, an online Google sheet… you name it! It’s that variety of context that makes building graphs more than simply having a database in your local project — where there is data, there is a way.
That’s pretty much what...
Quick and Simple Search Filter Using Vanilla JavaScript

When building Single Page Applications a feature I frequently find myself adding is a simple search filter. Nothing too in depth, I'll just want a text field to be able to quickly filter over items
Perceived Velocity through Version Numbers
30.4.2019
HTML5 and CSS3 were big. So big that they were buzzwords that actually meant something and were a massive success story in pushing web technology forward. JavaScript names their big releases now too: ES6, ES7, ES8... and it seems like it will keep going that way.
But HTML and CSS are done with that...
JavaScript Detect Async Function
29.4.2019
JavaScript async/await has changed the landscape of how we code. We’re no longer stuck in callback or then hell, and our code can feel more “top down” again. Async functions require the following syntax: async function myFunction() { } To use await with a function, the function...
That Time I Tried Browsing the Web Without CSS
24.4.2019
CSS is what gives every website its design. Websites sure aren’t very fun and friendly without it! I’ve read about somebody going a week without JavaScript and how the experience resulted in websites that were faster, though certain aspects of them would not function as expected.
But CSS. Turning...
