@braindouche No, that's a perfectly reasonable expectation, but the hiring/interviewing process does need to specifically select for it.
Anyone who can't do regular HTML and JS should not call themselves a web developer and should not be hired as one.
@LouisIngenthron
In their defense, when they were hired the company didn't need those skills, so there was no need to select for them. I'm the maniac insisting on developing without libraries and I'm the new kid.
