Hear me out. I have reason to believe Big Tech has established an over-leveraged short position in Backbone.js. If we all migrate to Backbone.js and refuse to ever migrate off, it'll create a massive short squeeze on their tech debt that they won't be able to recover from. #💎✋
When you finally make it into the Spec
Quick review on TC39 process: Proposals go through a 5-stage process (numbered 0-4, because of course it is), with each stage requiring an additional level of approval and commitment from members of the TC39 committee. The amount of time required to clear all 5 stages can vary widely -- some proposals are approved in months, others get stuck on one or more stages for years at time (kinda like a game of Phase 10 from hell).
We'll run through all five new features and give each one a hotness rating on a scale of 1-5 🔥. Why? Because we've been watching too much Bachelor/Bachelorette in quarantine like everybody else.
Promise.any() -- This new method for promise will resolves if any one of the supplied promises are resolved. 🔥 Rating: 2/5 -- I'm sure there are some fantastic use cases for this that one of the 80,000 of you will tell me about while also being upset it only got a 2, but I can't think of any.
WeakRef is a new class that lets you create weak references to objects, AKA references that won't stop the referenced objects from being garbage-collected. The main use case for this would be to implement caches or mappings to large objects.
🔥 Rating: 3/5 -- Pretty cool in theory, but you'll probably never use it in practice.
String's replaceAll() Method -- Lets you replace all occurrences of a string with another string value; kinda like "Find and Replace" in Microsoft Word.
🔥 Hottness Rating: 3/5 -- Not ground breaking, but on more than one occasion I've been upset that
replace only actually worked on the first occurrence.
Logical assignment operators -- This feature was ~~lifted from~~ inspired by Ruby, and it combines logical operations (
??) with assignment (
a ||= b,
a &&= b,
a ??= b). There's a lot more to explain here, but we're running out of space.
🔥 Rating: 4/5 -- Combining two concepts into one new feature like this is pretty exciting.
Numeric separators -- Helps make numeric literals more readable by using
_ to create a visual separation between groups of digits. So instead of
let billion = 1000000000, you can do
let billion = 1_000_000_000.
🔥 Rating: 5/5 -- No more squinting and counting the digits with your cursor 4 times to make sure you got it right??? We're smokin' meats now!
Which framework are we pumping today, folks?

The most commented-on post: "Nobody talks about the real reason to use Tabs over Spaces" by u/ChaseMoskal, predictably had a lot of people ready to fight to the death in the comments for their beliefs.
Look how far we've come, together 💖.
window.location.href. I think it's also worth noting that
window.location has a bunch of different properties on it that may be of use to you as well.
Let's assume this is the current URL we're on
These are all the properties that
window.location gives us.
Last week, we made a joke about how "AnimeXYZ would be a great name for an animation library that makes a tiny Naruto run across the bottom of your screen every time a new page loads." And in a matter of hours, I was reminded why we have the best readers on the planet. I present to you a fully-functioning AnimeXYZ -- courtesy of Jordan Gardner.
Dave Geddes wrote about how to practicie CSS like an artist. That's cool, but don't you think Michelangelo could've painted the Sistine Chapel wayyyy faster using a cookie-cutter Bootstrap template?
TOAST UI Chart just released v4.0 of its chart library. This should make it easier than ever to track your portfolio, especially when you consider the fact that stonks only go up 💎🤲.
Dave Plummer -- a retired OS engineer from Microsoft made an awesome video on the secret history of Windows bluescreens, which answers the age-old question, "why are blue screens blue?"
Fireship made a great video breaking down all of the AWS vs. Elasticsearch drama. TL;DR -- everyone loses, except Amazon (like always).
Stackshare just released their list of top 100 developer tools for 2020, which seems weird considering it feels like 2020 ended like 8 months ago. Congrats to this guy for taking the top spot (again).

This is the first ever newsletter that I open a music playlist for and maximize my browser window just to read it in peace. Kudos to @uidotdev for great weekly content.
The Bytes newsletter is a work of art! It's the only dev newsletter I'm subscribed too. They somehow take semi boring stuff and infuse it with just the right amount of comedy to make you chuckle.
Bytes has been my favorite newsletter since its inception. It's my favorite thing I look forward to on Mondays. Goes great with a hot cup of coffee!
I subscribe to A LOT of dev (especially JS/TS/Node) newsletters and Bytes by @uidotdev is always such a welcomed, enjoyable change of pace to most (funny, lighthearted, etc) but still comprehensive/useful.
Literally the only newsletter I’m waiting for every week.
Bytes is the developer newsletter I most look forward to each week. Great balance of content and context! Thanks @uidotdev.
The sense of humor and structure of the Bytes Newsletter is first class and the information that comes with it is enough to make a mini course.
Very few newsletters manage to be useful and not very boring. @uidotdev manages to achieve these pretty effortlessly. You can almost see Tyler chuckle as he writes them.
