Improve code that you wrote or maintain, through peer review.
Your question must contain code that is already working correctly, and the relevant code sections must be embedded in the question. Please avoid stripping out key details that may be relevant to the review. If your code is incomplete or not working, you should ask for help on another site.
You may wish to mention specific concerns: performance, security issues, etc.
We recommend reading our Guide to Asking Questions.
If your question is about this website, ask it on meta instead.
► create code fences with backticks ` or tildes ~

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
► complete the sentence: my question is about...
► use tags that describe things or concepts that are essential, not incidental to your question
► favor using existing popular tags
► read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
► combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
► creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
