A Simple CMS
WordPress is easy especially for the angular community. According to Roy, developers can just take an API and do whatever they can. The difficulty lies in having WP on the backend, and telling developers that they don't need to build their own CMS.
At present, the community favors React. This is due to Automattic's release of Calypso, an admin tool that's built on React. Lots of other initiatives are also built on React.
Learning Different Frameworks
As Roy puts it, there's a whole mix of frontend frameworks. But, Angular and React remains the big players in the field. Roy recently made a video course on YouTube regarding the pros and cons of different frameworks.
