ESNext: Proposals to look forward to (Full Stack Ghent)
Yesterday I was invited as a speaker at the March 2019 Meetup by “Full Stack Ghent” (their first one!) at the Clarabridge CX Social offices. At the meetup I gave a reprise of the talk “ESNext: Proposals to look forward to”, which I had already done at a Full Stack Antwerp meetup, a few months […]
ESNext: Proposals to look forward to
Yesterday I was invited as a speaker at the Full Stack Antwerp December 2018 Meetup at icapps. At the meetup I gave an adaptation of my talk “What’s Next for JavaScript”. The talk itself – which got renamed to “ESNext: Proposals to look forward to” – goes more into depth onto the proposals themselves, and […]
A minimal guide to ECMAScript Decorators (and Property Descriptors)
Very insightful piece by Uday Hiwarale on ES Decorators (Class Method Decorators, Class Instance Field Decorators, and Class Decorators). Right now (June 2018), Decorators are in stage 2 and we have Babel plugin to transpile decorators babel-plugin-transform-decorators-legacy. In stage 2, as syntax of the feature is subjected to change, it’s not recommended to use it […]
RE: The React is “just” JavaScript Myth
🗣 This was originally posted as a reply over at Dave’s blog. Unfortunately Disqus – the commenting system Dave uses – thinks it’s spam, so I’m posting it here as a full post instead. In his blogpost The React is “just” JavaScript Myth, Dave Rupert said this: React shows up on the scene with Babel, […]
What’s next for JavaScript? – A talk on ESNext by @bramus
I’m currently in Utrecht for Frontend United and have just finished my talk ”What’s next for JavaScript?”. Earlier this week I also gave a shortened version of this lecture at JSConf.be With ES2015 a lot has changed in JavaScript-land. Lesser known releases are the ES2016 and ES2017 releases. This talk not only touches these two […]
ESNext: JavaScript “Nullish Coalescing Operator”
One of my favorite ECMAScript Proposals is the “Optional Chaining Operator”. Another proposal that forms great duo with it is the “Nullish Coalescing Operator” (sometimes also referred to as “Nullary Coalescing Operator”). Both proposals still are Stage-1, but don’t let that stop us from taking a peek into it right now. Stage-1? 💁♂️ The TC39 […]

At the latest TC39 meeting the new features that will make it into the “ECMAScript® 2018 Language Specification” (ES2018) have been selected.

JavaScript: Removing a property from an object immutably by destructuring it
Say you have a JavaScript object like this: const user = { firstName: ‘Bramus’, lastName: ‘Van Damme’, twitter: ‘bramus’, city: ‘Vinkt’, email: ‘[email protected]’, }; And now say you want to create a copy of the whole object, except for the email property. The first idea that came to my mind was to clone/copy it and […]
Cancel a JavaScript Promise with AbortController
👋 This post also got published on Medium. If you like it, please give it some love a clap over there. In How to Cancel Your Promise Seva Zaikov has done a nice writeup on several techniques on how to cancel promises. After also touching generators and async/await the conclusion is that you can’t actually […]
