Speaking of code editors -
Can we just acknowledge how mouth watering this typeface from @jetbrains is?

A few weeks ago, you all told us your favorite code editor. VS Code won by a longshot.
What's your favorite extension or shortcut for @code?

This is … a great article.
In JavaScript, ellipses (…) are used for two separate shorthands — rest syntax and spread syntax. Let's find out how they work...

Someday @codingyuri will see the yellow-hued light 💛We're partial to technical writers around here, so we'll let this one slide

Arrays are usually a landmine for beginners with JS. These examples make it clear how to filter through them.

Beautiful! findIndex() is super powerful.
💛 JavaScript tip 💛
indexOf uses strict equality comparison under the hood.
This means it can only ever find the exact reference but not an identical object.
'findIndex' fixes this because you can pass a callback you can use to identify an object. ↓
![// won't work const array = [
{ prop: 1 },
{ prop: 2 }
];
const indexOfObject = array.indexOf({ prop: 1 });
// => -1 !
// this will work
const array = [
{ prop: 1 },
{ prop: 2 }
];
const indexOfObject = array.findIndex((element) => element.prop === 1);
// => 0 !](/pic/https%3A%2F%2Fpbs%2Etwimg%2Ecom%2Fmedia%2FFRvU837WYAE9DK%2D%2Ejpg%3Fname%3Dsmall%26format%3Dwebp)
ALT // won't work const array = [ { prop: 1 }, { prop: 2 } ]; const indexOfObject = array.indexOf({ prop: 1 }); // => -1 ! // this will work const array = [ { prop: 1 }, { prop: 2 } ]; const indexOfObject = array.findIndex((element) => element.prop === 1); // => 0 !
Just curious, are you using => functions exclusively or still sticking to traditional function syntax?
No judgement!
A spicy take that is also…hydrating? Who knew it could be done! 🌶️
Curious to hear the JS community's take on this!
"DRY" is an acronym introduced, seemingly universally, to software engineers early in their education.
