Nalezeno "JavaScript": 803

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...

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...

Convert Video to Grayscale

24.4.2019
I’m a JavaScript fanatic but I’ve always been fascinated with media manipulation. Maybe it’s because I’ve secretly always wanted to be a designer, but I’m fine with being able to manipulate art with software instead of create the art myself. One type of art I’ve...

Netlify Functions for Sending Emails

23.4.2019
Let's say you're rocking a JAMstack-style site (no server-side languages in use), but you want to do something rather dynamic like send an email. Not a problem! That's the whole point of JAMstack. It's not just static hosting. It's that plus doing anything else you wanna do through JavaScript...

Could Grouping HTML Classes Make Them More Readable?

22.4.2019
You can have multiple classes on an HTML element: <div class="module p-2"></div> Nothing incorrect or invalid there at all. It has two classes. In CSS, both of these will apply: .module { } .p-2 { } const div...

Tabs: It’s Complicated™

19.4.2019
I've said before one quick and powerful thing you can learn as a front-end developer just getting starting with JavaScript is changing classes. const button = document.querySelector(".my-button"); const element = document.querySelector(".content"); button.addEventListener("click", function()...

Clever code

17.4.2019
This week, Chris Ferdinandi examined a clever JavaScript snippet, one that's written creatively with new syntax features, but is perhaps less readable and performant. It's a quick read, but his callout of our industry's fixation on cleverness is worth... calling out: ...we’ve become obsessed as...

16.4.2019
Just like every other programming language, JavaScript has dozens of tricks to accomplish both easy and difficult tasks. Some tricks are widely known while others are enough to blow your mind. Let’s have a look at {x} JavaScript tricks you can start using today! Get Unique Values of an Array...

Edge Goes Chromium: What Does it Mean for Front-End Developers?

11.4.2019
In December 2018, Microsoft announced that Edge would adopt Chromium, the open source project that powers Google Chrome. Many within the industry reacted with sadness at the loss of browser diversity. Personally, I was jubilant. An official release date has yet to be announced, but it will be...

Get a CSS Custom Property Value with JavaScript

11.4.2019
Here’s a neat trick from Andy Bell where he uses CSS Custom Properties to check if a particular CSS feature is supported by using JavaScript. Basically, he's using the ability CSS has to check for browser support on a particular property, setting a custom property that returns a value of either...

In Defense of the Ternary Statement

10.4.2019
Some months ago I was on Hacker News (as one does) and I ran across a (now deleted) article about not using if statements. If you’re new to this idea (like I was), you’re in a for a real treat. Just search for "if statements" on Hacker News. You'll get articles proposing that you might not need...

Undefined: The Third Boolean Value

5.4.2019
I wanted to implement a notification message in one of my projects, similar to what you’d see in Google Docs while a document is saving. In other words, a message shows up indicating that the document is saving every time a change is made. Then, once the changes are saved, the message becomes: “All...
