Summary

In the last section, we explored the native XMLHttpRequest object and how it differs from other libraries for making service calls. In summary, as you can see, compared to jQuery, the native approach is a lot more verbose, difficult to work with, and low-level for most use cases. Unless you have a specific need where more control is required, I do not recommend its use.

In the next chapter, we will describe regular expressions, which are commonly used to match patterns in a concise, flexible, and efficient manner. We will also explore best practices for writing clean and understandable code, which is critical if you want your code to be easily maintainable and live for a long time.
