The PascalCase snake_case Algorithm
Converting between developer naming conventions correctly is non-trivial. Most tools just
lowercase everything - which breaks XMLParser should be
xml_parser, not x_m_l_parser.
Our engine uses a smarter regex that detects transitions between character categories:
// PascalCase / camelCase snake_case
str
.replace(/([A-Z]+)([A-Z][a-z])/g, '$1_$2') // XMLParser XML_Parser
.replace(/([a-z\d])([A-Z])/g, '$1_$2') // camelCase camel_Case
.toLowerCase() // camel_case
When to Use Each Case Format
