Python Jumps to #1 on GitHub Over JavaScript, But… — GitHub Universe took place this week, flooding us with data about how folks are using the platform. Of interest to those on social media was that Python has taken JavaScript’s #1 language crown, though many argued that TypeScript (now #3) made an impact here. In positive news, JS still ranks first for code pushes alone and there’s been a 15% jump in npm package consumption in the past year.

Should JavaScript Be Split Into Two Languages? — Two weeks ago we linked to an interesting slidedeck presented at TC39 where it was proposed to split JavaScript into two languages: a basic core and a fully featured version that needs tooling to compile it down. This covers a bit more of the story and led to a particularly extensive Hacker News discussion too.
