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

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”).

The first idea that came to my mind was to clone/copy it and […]
Cancel a JavaScript Promise with AbortController

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 […]
What’s new in JavaScript? ES2017 Language Features
The ECMAScript 2017 Language Specification – the 8th edition of the spec – was officially released at the end of June by TC39. 💁♂️ ICYWW: Should we say ES2017 or ES8? → Say ES2017. Back in the day ES6 was (and still is) used a lot to refer to ES2015, but one should be referring […]
