Frequently Asked Questions
How does _.camelCase() handle non-alphanumeric characters?
_.camelCase() removes non-alphanumeric characters and uses the remaining characters to form the camel case string.
Can _.camelCase() handle strings with multiple consecutive special characters?
Yes, _.camelCase() effectively ignores multiple consecutive special characters, treating them as a single separator.
Is _.camelCase() suitable for all naming conventions?
While _.camelCase() is ideal for converting strings to camel case, other naming conventions like snake case or kebab case require different methods or custom logic.
Conclusion
Lodash's _.camelCase() method is a straightforward and efficient way to convert strings of various formats to camel case notation. It's particularly useful for standardizing strings for variable naming, user input processing, and ensuring conformity with common programming style guidelines.
