The world of front end frameworks is always evolving. For years it was dominated by jQuery and Backbone, but these days we hear most talk about React and Vue.

Maybe you’ve heard of Fetch? The promise-based Web API for making network requests in the browser, and a favourite amongst developers. If you paste fetch(‘https://www.google.com’) into the Chrome DevTools console and run it you can take a closer look at how it works. Sadly, you can’t do the same in Internet Explorer. It won’t work.

I used to think that feature switches were clunky if-statements in my code that would require re-compilation or at least restart of my app. Launch Darkly proved me totally wrong, swinging me from cynical scepticism to deep love!

Modern frameworks are easy to learn. From zero web experience, they help you get productive in a matter of weeks. But for me, the web remained a mystery until I taught myself the very basics.

In this article, I will present to you some resources which can be useful to know about if you want to learn JavaScript, or in general, want to learn more about the language.

Every team has to make various decisions before, and during, the development of a digital product. One of these usually involves yarn, npm or another tool to build and package javascript code. Some developers have a burning desire to go in a certain direction, and sometimes they end up spending a considerable amount of time trying to make decisions that in fact will have little impact in their everyday life.
