Open source libraries inside the WordPress core

As mentioned earlier, there are several libraries available within the core that have yet to be noticed by many WordPress developers. Most beginner-level developers tend to include such libraries in their plugins when it's already available inside the core framework. This happens purely due to the nature of WordPress development, where most of the development is done for generic websites with very limited dynamic content.

As we move into web application development, we should understand the need for using existing libraries whenever possible due to the following reasons:

• WordPress contains libraries that are more stable and compatible

• This also prevents the duplication of libraries and reduces the size of the project files

I am sure you are familiar with libraries and plugins such as jQuery and TinyMCE within WordPress. Let's discover the lesser known and recently added libraries in order to make full use of them with web applications.
