Скачать или смотреть Simple Algorithms in JS: Converting kebab-case to camelCase

I type out and discuss two JavaScript functions that take in a kebab-case string and return a camelCase string. This is an exercise in thinking through simple algorithms, using built-in methods like split and map, and a new favorite bit of syntactic sugar: array destructuring.

Algorithm 1: The "Brute Force" Method
Loop through each character in the array. Use a boolean variable to keep track of encountering a dash, and capitalize the next character.
A mistake in the code: The code does not correct for the presence of upper-case characters. The simplest fix would be to call toLowerCase on the input string.

Algorithm 2:
Use split, map, substring, and join to achieve the same goal.

Coding Challenge:
Can you think of a way to use array destructing to rewrite the titleCase function without the use of the substring method? (Strings can be treated as arrays.)
