+Creates a deep clone of an object.
 Clones primitives, arrays and objects, excluding class instances.
 
 - Use recursion.
 - Check if the passed object is `null` and, if so, return `null`.
 - Use `Object.assign()` and an empty object (`{}`) to create a shallow clone of the original.
 - Use `Object.keys()` and `Array.prototype.forEach()` to determine which key-value pairs need to be deep cloned.
-- If the object is an `Array`, set the `clone`'s `length` to that of the original and use `Array.from(clone)` to create a clone.

 Creates a new string with the results of calling a provided function on every character in the given string.
