 Flattens an object with the paths for keys.
 
 - Use recursion.
-- Use `Object.keys(obj)` combined with `Array.prototype.reduce()` to convert every leaf node to a flattened path node.
+- Use `Object.keys()` combined with `Array.prototype.reduce()` to convert every leaf node to a flattened path node.
 - If the value of a key is an object, the function calls itself with the appropriate `prefix` to create the path using `Object.assign()`.
 - Otherwise, it adds the appropriate prefixed key-value pair to the accumulator object.
 - You should always omit the second argument, `prefix`, unless you want every key to have a prefix.
