JavaScript's Creator Recommends We Call JavaScript 'JS' — In response to a lively Twitter thread this week posing the question “If you were given the chance to rename JavaScript, what would you call it?” Brendan Eich wisely suggested, nay declared, we go with JS. While there’s an aspect of fun around this whole debate, it seems a sensible idea given JS has no relation to Java at all, although it might take us a while to rebrand ;-)


A Brief Status Update on Vue 3.0 — The 18th beta of Vue 3.0 is out. Amongst other things, they’re targeting mid July for the first release candidate, then early August for the final Vue 3.0 release. You’re encouraged to start using it already though.

Announcing TypeScript 4.0 Beta — Last week we said the TS 4 beta was “due any moment” and last thing on a Friday was clearly the time to shine 😂 4.0 has no substantial breaking changes but there are lots of bits and pieces to play with including variadic tuple types, short-circuiting assignment operators, and editor improvements.

V8 Release V8.4 — The next release of V8 (due to come out in coordinate with Chrome 84) boasts improved startup time, support for weak references and finalizers (worth seeing the code examples for these advanced features), and private methods and accessors.

Understanding Template Literals — I really like Tania’s tutorials as they are both straightforward and thorough. Template literals are a piece of syntax (introduced in ES6/ES2015) worth understanding if you don’t use them yet.

The !! Operator and a Misunderstanding of How JS Handles Truthy / Falsy Values — Ben Nadel has noticed developers using the double-bang (!!) operator far more often in their JavaScript code than they have to. As such, he provides a series of unnecessary examples followed by cleaner, more intuitive examples.
