Yes, for beginner programmers syntax is a huge deal. Sticking to something consistent as one starts out prevents conflating variations of design (encapsulation, coherence, atomicity) with variations of punctuation.
Well then at what point will they be learning the syntax of another language? They’d be well past the point of beginner by then, no? And even if they’d be in a junior role (assuming junior = beginner), how much does any of this talk actually matter when the job demands that an employee learn a language anyway?
