Orthogonality is a somewhat fancy, definitely mathematical word. But it’s a crucial property of good developer experiences. From programming languages to API design, orthogonality makes all the difference between experiences that “just work” and experiences that are frustrating.
What is Orthogonality? Orthogonality is a mathematical term that shows up in several mathematical fields. The most common one is geometry, where lines that are orthogonal are said to intersect at a 90 degree angle and be perpendicular.
