[SOLVED] How to control the range used by map() function

Question

This code was supposed to format some string into snake_case and camelCase. Recently I learned that I was making the code to generate a PascalCase rather than camelCase result.

My question is, how do I make the call to map() at line 15 to ignore the first element, and to only capitalize first letter of the second to the last element.

* Illustration:

I want this ...
[ "hello", "world" ] becomes "helloWorld" (camelCase)

But I currently have ...
[ "hello", "world" ] becomes "HelloWord" (PascalCase)

Answer 1

Just a thought, can't you just do something like this with the output..
Like,
str = HelloWorld

firstChar(str).toLowerCase + str.substring(1)
___

Or if you want to maintain a one-liner .mapIndexed can help you in what you want to achieve.
