How should formats and mixins be named according to best practices?

Naming formats and mixins by purpose rather than appearance is essential in ensuring that the code is maintainable, clear, and scalable. When names reflect functional intent, they enhance the overall understanding of the code for any developer who may work on it in the future. This approach allows for easier collaboration and modification, as developers can identify the role of each format or mixin without needing to delve into the specific visual details.

For example, a mixin named "responsiveButton" clearly indicates its purpose in enhancing the responsiveness of a button, whereas a name focused solely on appearance, like "redRoundedButton," does not convey the functional role it serves in the broader design context. When developers adopt a purpose-driven naming convention, they improve communication and the ability to build upon existing components without confusion or ambiguity.

This practice also fosters an environment where updates to visual aspects can be made without affecting the underlying purpose, leading to a more flexible and agile development process. Therefore, adopting a purpose-based naming strategy aligns with the best practices for developing robust, user-friendly interfaces in Pega.
