As you can see in the replies people translate their lived experience writing code and answer art or science based on however they conceptualize and practice programming. A few years ago MIT conducted a study that concluded "reading computer code is not the same as reading language", answering the question of whether coding is art or science with a rigorously documented "both". Despite the fact that programming looks like art and looks like science, I still think there's a concept that better fits the practice of coding, creative expression.
