+* Finds the index of the first item in an array that has a specific property, where the property name is provided as a PropertyKey.
+*
+* @template T
+* @param arr - The array to search through.
+* @param doesMatch - The criteria to match against the items in the array. This can be a function, a partial object, a key-value pair, or a property name.
+* @param propertyToCheck - The property name to check for in the items of the array.
+* @param [fromIndex=0] - The index to start the search from, defaults to 0.
+* @returns The index of the first item that has the specified property, or `-1` if no match is found.
+*
+* @example
+* // Using a property name
+* const items = [{ id: 1, name: 'Alice' }, { id: 2, name: 'Bob' }];
+* const result = findIndex(items, 'name');
