Frequently Asked Questions 常见问题

• When should I use camelCase vs snake_case? — camelCase and PascalCase are common in JavaScript, Java, C#, and TypeScript. snake_case is standard in Python, Ruby, and SQL. kebab-case is used in CSS, HTML attributes, and URLs.
• What is PascalCase? — PascalCase (also called UpperCamelCase) capitalizes the first letter of every word with no separators. Example: MyVariableName. It is used for class names in most languages.
• Does it handle spaces and special characters? — Yes. The converter intelligently splits on spaces, underscores, hyphens, and capital letters to correctly parse words before applying the target format.

• 什么时候用 camelCase 还是 snake_case？ — camelCase 和 PascalCase 常用于 JavaScript、Java、C# 和 TypeScript。snake_case 是 Python、Ruby 和 SQL 的标准。kebab-case 用于 CSS、HTML 属性和 URL。
• 什么是 PascalCase？ — PascalCase（也叫 UpperCamelCase）将每个单词的首字母大写，不使用分隔符。例如：MyVariableName。多数语言中用于类名。
• 能处理空格和特殊字符吗？ — 能。转换器智能地在空格、下划线、连字符和大写字母处分割单词，然后应用目标格式。
