JS Practice — Built-in Objects

Advanced — toCamelCase

📖 Usage Example

toCamelCase('hello_world')   // → 'helloWorld'
toCamelCase('foo_bar_baz')   // → 'fooBarBaz'

toCamelCase converts snake_case strings to camelCase by capitalizing letters after underscores.

Advanced: String Transformation — camelCase

Challenge: Implement toCamelCase(str: string): string converting a snake_case or kebab-case string to camelCase.

toCamelCase('hello_world')    // → 'helloWorld'
toCamelCase('foo-bar-baz')    // → 'fooBarBaz'

💡 Hints (1)

• A regex replacing [-_] followed by a char, capitalizing that char, works cleanly.
