You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "4111-1111-1111-1111",
  "5500000000000004",
  "6011 0000 0000 0004",
  "2023/12/31 23:59:59",
  "29.02.2024",
  "2001:0db8:85a3:0000:0000:8a2e:0370:7334",
  "2001:0db8:85a3::8a2e:0370:7334",
  "FE80:0000:0000:0000:0202:B3FF:FE1E:8329",
  "function_name123",
  "_validUnderscoreStart",
  "CamelCaseIsValid",
  "snake_case_valid_2"
]

Rules:
1. Your regex must match ALL of the target items in the text.
2. Your regex must NOT match anything else in the text.
3. The pattern should be a valid JavaScript regular expression.
4. Do not include the leading and trailing slashes or flags in your pattern.

You'll use the "make_move" function to submit your solution with:
1. reasoning: Your reasoning for this regex pattern
2. move: The regex pattern as a simple string

Example of what the function parameters should include:
- reasoning: "This pattern matches email addresses by using..."
- move: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}"

IMPORTANT:
- The regex pattern should be a simple string.
- Do NOT use raw regex notation with slashes like /pattern/.
- Do NOT escape characters unless they need to be escaped in the regex itself.
- For example, to match parentheses, use "\(\)" not "\\(\\)".
- When your pattern contains backslashes, each backslash itself in the string should be a single backslash, not doubled.

Think carefully and test your pattern mentally before submitting.
