Are there any up to date tutorials for coding? I am looking for one.
You could rea the DM Guide acompained by the Reference.
As it may be a bit messy for new comers, you could read some of Falacy's and others tutorials on the Tutorials & Snippets section.

Most of the articles here. Some of them are old yes, but their wisdom still holds true to this day.
