Hello everyone and welcome back to another episode of Front End News. I hope you will find the following topics both interesting and useful.


Introducing Deno

The Cute Deno

Image source: https://deno.land/v1

For many years NodeJS has been the platform of choice for modern JavaScript development. However, many things have changed since its launch and the original creators of Node think the time has come to take the next step forward.

Say "Hello!" to Deno, a new runtime for executing JavaScript and TypeScript outside of the web browser. Will this cute-looking challenger overtake the old dinosaur? Only time will tell.


What's New In DevTools (Chrome 84)

In the wake of the Web Vitals last week, the team behind Google Chrome has given us a preview of what changes will happen in the Developer tools starting with Chrome 84.

Chrome 84 DevTools

The performance panel will include new ways to track Total Blocking Time (the main metric behind First Input Delay - FID) and Cumulative Layout Shift (CLS). Both FID and CLS are part of the Core Web Vitals we mentioned in the previous episode.

More details on this and the rest of the changes are available using the link below.
