ESNext: Proposals to look forward to (Full Stack Europe)

I’m currently in Antwerp for the first edition of Full Stack Europe, “The conference for the whole team”. Earlier this week I guided a workshop “React from Scratch”. After a small Lightning Talk yesterday on “JavaScript Yellow”, I today did a full talk named “ESNext: Proposals to look forward to” With the yearly ECMAScript releases […]

ESNext: Proposals to look forward to (Fronteers Jam Session)

At last years’ edition of Fronteers Conference I gave a lightning talk on ESNext, covering the TC39 Process and highlighting three of my favorite proposals (some of which have hit Stage-3 by now!). Earlier this week they released the video of my (short) talk The lightning talk itself was a short version of a full […]

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 […]

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 […]

JavaScript: What’s new in ECMAScript 2018 (ES2018)?

👋 This post also got published on Medium. If you like it, please give it some love a clap over there. At the latest TC39 meeting the new features that will make it into the “ECMAScript® 2018 Language Specification” (ES2018) have been selected. All proposals that have reached stage-4 since the consolidation of ES2017 got […]

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 […]

ESNext: JavaScript “Optional Chaining Operator”

UPDATE: The proposed operator got renamed from “Null Propagation Operator” to “Optional Chaining Operator”. This post has been updated to include this change. Earlier today I was delighted to see that the “Optional Chaining Operator” in JavaScript has entered stage-1. This little gem – which I know from Coffeescript – is a real timesaver, and […]

ES6 ES2015: Looping over an Object with keys and values

Say you have an object like this: const obj = { firstName: ‘John’, lastName: ‘Doe’, age: 50, eyeColor: ‘blue’ }; Using lodash’s forEach you can easily loop over this object, with easy access to both the key and the value: _.forEach(obj, function(value, key) { console.log(key + ‘ ‘ + value); }); But what about ES2015?
