Questions, answered

Does title case follow a specific style guide?

It capitalizes the first letter of every word. It does not apply editorial exceptions for words such as “and” or “the”.

How are code identifiers converted?

The tool detects word boundaries, including common camelCase boundaries, then removes separators. It does not check whether the result is a legal identifier in a specific programming language.
