All the modern browsers support native Ja*aScript modules, and it’s a perfect time to start using them, which will change the way we are bundling the Ja*aScript using Webpack, Rollup, and other bundlers, and how the code is executed. We will take a look how they work, what is the level of support in the browsers and Node.js, plus main findings and gotchas on the way of Looking into examples, we will understand the native modules features, performance details and lazy loading JS modules techniques. Today CSS Custom Properties are supported in all the major browsers. Now it’s time to do the next step- to have an ability to register new Custom Properties from Ja*aScript and setup the browser how to work with them (e.g. real CSS polyfills). They should work with the same performance as the native CSS properties, being animatable and Custom Properties can be used as a bridge between CSS and Ja*aScript. Houdini Task force introduces specs and Ja*aScript Worklets to expose the interaction with previously fully internal browser rendering mechanisms (during Paint, Layout, Composite stages). All this brings Front-End development to the next level, parts of which are already available for the developers. How often have you applied the Ja*aScript or CSS solution considered as an optimization, and after couldn’t find an easy way to measure how effective it was? Of course, you have the performance timeline recording, but in most cases, it provides the retrospective data, not the life-updated. For this and other performance-measuring techniques, Chrome DevTools added the “Performance Monitor” tab which represents the real-time app performance metrics: Since the Promises were added in Ja*aScript, one of the biggest concerns was the absence of an ability to easily apply some code after the Promise is fulfilled (after both success and reject actions). There are many examples of such a need: showing a loader when the request to the server is in flight or even a simpler case- when we just want to log the completion of the operation regardless of how it
