In particular, it allowed for organizing common traits (such as extensibility, or different ways of showing examples as schemas that can be mixed in to the main object definitions.

The consumer component will barely change from our last example. The only difference is the way we'll get a reference to our store (since now the store is exported from the JS module):

It must be called during the component's initialisation (but doesn't need to live inside the component; it can be called from an external module).

Refactoring at scale is challenging and a significant investment, so communicating the progress is important both from a business perspective but also as a motivational effect to developers. In this case we used a combination of complexity trend visualizations and Code Health Metric as shown in the preceding example.

Here are few, real-life commits of refactorings that make use of this solution:

What is code refactoring?Code refactoring means restructuring your existing code, in a way that improves the internal structure but doesn’t change its external behavior. This complex procedure is aimed at modernizing software. It is typically used to increase the system’s maintainability, enhance performance, scalability, security and so on. If performed well, it can help developers discover some hidden bugs or vulnerabilities in the system.Typically, refactoring is done in small steps, called micro-refactorings. Each of these steps is usually a tiny change to a source code that leaves the functionality of the system unchanged, it just makes the code cleaner and simpler. And if you do want to change some functionality of your code, it’s much easier to do with a clean, refactored code.
