Implement a function selectData(rows, predicate) that filters rows of data based on a dynamic predicate.

The function should:

• Accept an array of objects (rows) representing a dataset.
• Accept a predicate function or an object specifying multiple conditions.
• Support deep property access (e.g., 'user.address.city').
• Allow combining conditions using AND / OR logic.
• Handle arrays and nested objects within the rows gracefully.
• Return a new array of rows matching all conditions.

Examples

const data = [
  { id: 1, user: { name: 'Alice', age: 25 } },
  { id: 2, user: { name: 'Bob', age: 30 } },
  { id: 3, user: { name: 'Charlie', age: 30 } },
];

// Using a predicate function
selectData(data, row => row.user.age === 30);
// returns [{ id: 2, ... }, { id: 3, ... }]

// Using a conditions object
selectData(data, { 'user.age': 30, 'user.name': 'Bob' });
// returns [{ id: 2, user: { name: 'Bob', age: 30 } }]
