Similar to `decamelize-keys`, `humps` can also convert keys between camelCase and snake_case. However, `humps` provides more comprehensive options for both decamelizing and camelizing keys, making it a versatile choice for different case conversion needs.
The `snakeize` package is focused on converting object keys to snake_case. While it serves a similar purpose to `decamelize-keys` in terms of changing the case of keys, it is specifically tailored for snake_case conversion without the flexibility of choosing a custom separator.
As the inverse of `decamelize-keys`, `camelcase-keys` converts object keys from snake_case or kebab-case to camelCase. It's useful for scenarios where you need to convert data to match JavaScript's naming conventions, offering a complementary functionality.
