Detect Generator Functions with JavaScript

23.11.2020
In the current JavaScript climate of new syntaxes, features, and using loads of external libraries, it seems harder than ever to be sure what your functions are being given or even what the data represents. Of course, we’ve come up with Flow and TypeScript to help, but we can’t count...

git: Remove Untracked Files

19.11.2020
I’ve always said that I know just enough about git to get the job done, but also do something destructive. Nothing embodies that more than my recent mistake. I somehow found a git repository full of untracked files and git stash wouldn’t fix it. Desperation led me to learning how...

Node isConnected

13.11.2020
Every so often I discover a property in JavaScript objects that I didn’t know existed, oftentimes using another trick to accomplish the same functionality. One such property I just learned about was isConnected, a node property that attached to a context (i.e. document). Here’s how...

How to Prevent Pasting into an Input

19.10.2020
Every once in a while I get to a website that doesn’t allow me to paste into a form input. In most cases it’s something to do with login credentials (username and or password) and auth codes. So how are they preventing me from pasting information? It’s as easy as you’d...

How to Conditionally Add Attributes to Objects

16.10.2020
JavaScript is full of tricks that you don’t know you want until you … want … them. Or maybe just until you see them. One trick I recently realized was conditionally adding attributes to React elements. Of course this trick essentially boils down to conditionally adding properties...

How to Create an Async Function

24.9.2020
One thing I love about JavaScript is that there are many ways to accomplish the same task, one such example being creating functions. There are several patterns for functions; one of the last you see used is the new Function method: /* new Function(arg1, arg2 (...), body) */ const myFunction =...

Remove the Search Input Clear(x) Icon

21.9.2020
I really appreciate the amount of different <input> elements we’ve received over the past decade. These elements don’t just bring a new semantic advantage, but also provide UI helpers, which in many cases are useful. In a recent case, I found a UI element not useful: the x (clear)...

How a Spoof Turned Into a Media Hype About Bitcoin Cash

19.9.2020
An anonymous Bitcoin Cash (BCH) supporter says he deliberately started a spoof which successfully baited local media to report on the coin. The trick, which involved the use of 100 Bitcoin Cash tip stickers, only cost a total of $1,100 yet it managed to get BCH featured by media outlets...

Logical Assignment Operators

10.9.2020
I love JavaScript, it’s my favorite programming language, but I love dipping into other languages because they offer a new perspective on coding paradigms. There’ve been syntax additions to JavaScript that I’ve seen I found interesting (think ?? in optional chaining) and now...

Match Emojis with Regular Expressions

19.8.2020
When experimenting with unicode property escapes, to identify accented letters in strings, it reminded me of a question I had a few years ago: what is the best way to identify and then replace emojis in a string? I first noticed this practice when using emojis in Facebook — sometimes Facebook...
