Does this PR introduce a breaking change? (check one)

• [x] Yes
• [ ] No

If yes, please describe the impact and migration path for existing applications: The main areas of improvement are:

Code readability The optimized code is more readable because it uses the optional chaining operator and the in operator to make the code more concise and eliminate unnecessary nested conditionals.

Performance The optimized code uses the delete operator directly and avoids the try-catch block for deleting properties from objects. This can improve performance because delete is a more efficient way to delete a property from an object than assigning it to undefined. Additionally, caching the result of toParamCase function reduces the number of function calls made.

Error handling The optimized code handles errors in a more elegant way. For example, if element is undefined or null, the optional chaining operator ?. will return undefined without throwing an error. Similarly, if element.dataset is undefined or null, the optional chaining operator will return undefined instead of throwing an error.
