Support us on Kofi!
Have you ever wondered if it's worth breaking the internet? No? Well, today's guest has! Tune in as we chat with Yulia Startsev, a software engineer for Mozilla, and a compiler for JavaScript. We dive into the conversation with who uses semi-colons (and when and why), followed by an anecdote from Yulia about Smoosh and the potential to break the internet. Yulia talks us through the considerations when naming a new JavaScript function, and the promising changes around immutability. We also learn how to remember the difference between the splice and slice functions, and why pattern matching is such an exciting prospect. We hear about the four stages of deciding to change JavaScript, why most programming languages are written in English, and why certain popular functions like caller and colleague were deprecated. We wrap up the episode with a summary of what the array by group function does, who funds the updates to JavaScript, and what Yulia’s fantasy changes to the web would be! So, for all this and so much more, tune in today.

“Pattern matching is a proposal I am quite excited about, switch in case statements are very interesting in JavaScript. By interesting, I mean, broken.” — @codehag [0:27:23]
“[Pattern matching is] very exciting. It's very, very powerful, which makes it a little scary because using an overpowered tool for something that doesn't need that level of power can lead you to making mistakes that you wouldn't make with a less powerful tool.” — @codehag [0:33:19]
“It’s significantly more difficult to remove something than it is to add something.” — @codehag [0:52:10]
