What is the definition of an engineer in your eyes? In some countries there is a legal definition, so developers are not allowed to call themselves engineers unless they have an engineering degree (and not the software kind).
It is not about my personal definition, there are even laws as you said.
I just find it silly to use a definition that you typically need 4-6 years of maths heavy formal education for front end javascript that you can learn on youtube in a month.
I'm one of those "real engineers" that studied 4-6 years of maths, and this gatekeeping feels very silly to me.
Some frontend developers are doing more actual engineering than I did when I was working as an actual electrical engineer, and I was working on buildings and shit.
Not all frontend devs, though, and certainly not the ones straight out of a bootcamp, but a lot are.
But the people building foundations for others to work on (like the target audience for this library) definitely are doing some sort of engineering.
