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...

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...

Converting Color Spaces in JavaScript

10.1.2019
A challenge I faced in building an image "emojifier" was that I needed to change the color spaces of values obtained using getImageData() from RGB to HSL. I used arrays of emojis arranged by brightness and saturation, and they were HSL-based for the best matches of average pixel colors with...

An Initial Implementation of clip-path: path();

24.12.2018
One thing that has long surprised (and saddened) me is that the clip-path property, as awesome as it is, only takes a few values. The circle() and ellipse() functions are nice, but hiding overflows and rounding with border-radius generally helps there already. Perhaps the most useful value...

Get Viewport Lines and Columns in CodeMirror
