Description

Reports class names that do not start with an uppercase letter or that contain underscores:

class user_profile { ... }     // FLAW — snake_case
class lowerName { ... }        // FLAW — starts with lowercase
class UserProfile { ... }      // OK

Rationale

The JavaScript and TypeScript ecosystems use UpperCamelCase (PascalCase) for class names without exception: every framework template generator (Angular CLI, React create-component, Vue CLI), every linter preset, and every IDE refactor assumes the shape. Deviations break copy-paste between codebases and confuse readers — class user_profile looks like a function or a variable, not a constructor.

Remediation

Rename the class to PascalCase:

class UserProfile { ... }
class HTTPClient { ... }       // initialisms still PascalCase, no underscores
