Replacing Recompose with React Hooks

Recompose is a React utility belt for function components and higher-order components that has been very useful to our frontend engineering team. After more than three years of working with it, we’ve identified a lot of pain points. In October 2018, the React team introduced Hooks which shipped with React v16.8 and provided an alternative to HOCs.

How to generate a constant request rate in k6?

There are two different categories of tools in the load testing ecosystem. The first category is called non-scriptable tools and are usually used for load testing either a single endpoint or a set of endpoints. These tools usually generate load using a constant rate, which is measured in requests per unit of time, usually seconds. These non-scriptable tools don't apply any logic to the load testing process, other than the generation of load.
