@@ -9,18 +9,14 @@ Unflatten an object with the paths for keys.
 - Split each key with a dot delimiter (`.`) using `Array.prototype.split('.')`and use `Array.prototype.reduce()` to convert flattened paths to leaf node.
 - If the current accumulator already contains 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 value as the accumulator.
