Beginners - DEV Community

For Questions...

Consider using this tag along with #help, if...

You are new to a language, or to programming in general,

You want an explanation with NO prerequisite knowledge required.

You want insight from more experienced developers.

Please do not use this tag if you are merely new to a tool, library, or framework.

For Articles...

Posts should be specifically geared towards true beginners (experience level 0-2 out of 10).

Posts should require NO prerequisite knowledge, except perhaps general (language-agnostic) essentials of programming.

Posts should NOT merely be for beginners to a tool, library, or framework.

If your article does not meet these qualifications, please select a different tag.

Promotional Rules

Posts should NOT primarily promote an external work. This is what Listings is for.

Otherwise accepable posts MAY include a brief (1-2 sentence) plug for another resource at the bottom.

Resource lists ARE acceptable if they follow these rules:

Include at least 3 distinct authors/creators.
Clearly indicate which resources are FREE, which require PII, and which cost money.
Do not use personal affiliate links to monetize.
Indicate at the top that the article contains promotional links.
