JS snake to camel case converter

snakeToCamel.js

/**
 * Converts a string in snake case to camel case and returns it.
 * Example "this_is_cool" => "thisIsCool"
 * ATTENTION: Expects the original string to be in valid snake case.
 * Will not perform any validation - invalid input creates invalid output!
