In this chapter, we looked into how we can integrate Web Components into already-existing projects that use some of the most famous libraries/frameworks in the frontend world. We learned how to add an existing web component built using Vanilla JavaScript to a React, Angular, or Vue project. The techniques learned in this chapter can be used with any framework or library and in any type of existing project. The inclusion of Web Components in already-existing projects is also a good use case for the quick prototyping of features, and the components can even be removed as soon as their work is done. 

I hope that this chapter was useful in helping you create better web applications, whether they use Web Components or not.
