Is it necessary to know Jinja2 to learn and understand Flask? And in practice it is an important element?

Question

Flask

Started learning Flask and came across Jinja2

Answer 1

Yes, definitely. You without jinj's are like without hands.

Answer 2

Watching what you are doing. jinja is a template engine, if you do not use it in your project, then God bless it.
Suppose for a simple API, html documents are not needed at all for their projects, and even more so with variable substitution, in fact, jinja is also not needed. Or if, nevertheless, html documents are used, but they are static, as in a business card site.
If Flask is used to write a full-fledged site, then jinja knowledge is indispensable.

Answer 3

necessarily. if you don't know Jinja2, then you don't pull on a jun. actually "what is there to know then?" regular template engine
