 Unflatten an object with the paths for keys.
 
-- Use `Object.keys(obj)` combined with `Array.prototype.reduce()` to convert flattened path node to a leaf node.
-- If the value of a key contains a dot delimiter (`.`), use `Array.prototype.split('.')`, string transformations and `JSON.parse()` to create an object, then `Object.assign()` to create the leaf node.
-- Otherwise, add the appropriate key-value pair to the accumulator object.
+- Use nested `Array.prototype.reduce()` to convert the flat path to a leaf node.
+- Use `String.prototype.split('.')` to split each key with a dot delimiter and `Array.prototype.reduce()` to add objects against the keys.
+- If the current accumulator already contains a value against a particular key, return its value as the next accumulator.
+- Otherwise, add the appropriate key-value pair to the accumulator object and return the value as the accumulator.
