What is DX? betta.io

Slide 24

Slide 24 text

“Developer experience is an extension of UX that focuses on the developer, who can either be the intermediary or, as is the case with many APIs, the end user. Whether or not you focus on DX design, your developers are always experiencing your API, and that experience may either be positive or negative.” betta.io - Jennifer Riggins | @jkriggins
