Question 1

How does the code line counter detect comments?

Accepted Answer

The tool uses language-specific comment patterns. For example, JavaScript uses // for single-line and /* */ for multi-line comments, Python uses # for single-line and triple quotes for multi-line. Select the correct language for accurate detection.

Question 2

What languages are supported?

Accepted Answer

Supported languages include JavaScript, TypeScript, Python, HTML, CSS, Java, C, C++, Go, Rust, Ruby, PHP, Swift, Kotlin, SQL, Shell/Bash, JSON, YAML, XML, and Markdown.

Question 3

What counts as a code line vs comment line?

Accepted Answer

A code line contains executable code or declarations. A comment line starts with a comment symbol or is inside a multi-line comment block. Blank lines (empty or whitespace-only) are counted separately. Lines with both code and comments are counted as code.
