What knowledge is needed for competent development on Wordpress/Bitrix?

Question

1C-Bitrix

Good day everyone, it's hard to formulate the question itself, but the situation is this:
There is a +/- functioning web studio working with WP using draw&drop (for the most part), but there are also 4 ready-made team members ready for active learning and willing to start work with normal projects.
The plan is to learn WP&Bitrix with a normal approach to development (for simple and medium projects) and (in a wonderful future) start working with some kind of framework (for complex projects).
Actually, the question is, what knowledge (other than marketing/design) is needed in order to be able to develop any projects on WP (including making your own interfaces / finishing or writing themes for the project / doing something interactive and complex)?
From ideas only learning HTML/CSS/PHP/JS/MySql to a normal level, but would really like to know your advice on what we are missing (which JS frameworks to learn, whether to learn SaaS/post/CSS pre-processors/ REST API, etc.)
I know, the question is a little unstructured, but I hope for help, thanks!

Answer 1

You need knowledge of PHP and WP, ​​at least.
PS Bitrix and "normal approach" are incompatible words.

Answer 2

You don’t need Bitrix, but WP, if only for a start, and then switch to normal frameworks like Laravel, Symphony, Yii2 - and it’s more interesting and you will earn more.

Answer 3

functioning web studio

- do not listen to the subjective opinions of techies, for doing business Bitrix is ​​suitable for any studio, if only because it allows you to earn money on the sale of licenses, license renewals, the sale of ready-made partner solutions, plus you can develop your own circulation solutions for the marketplace
