         * This is the core algorithm for matching up children.  The idea is to use id sets to try to match up
         * nodes as faithfully as possible.  We greedily match, which allows us to keep the algorithm fast, but
         * by using id sets, we are able to better match up with content deeper in the DOM.
         *
         * Basic algorithm is, for each node in the new content:
         *
         * - if we have reached the end of the old parent, append the new content
         * - if the new content has an id set match with the current insertion point, morph
         * - search for an id set match
         * - if id set match found, morph
         * - otherwise search for a "soft" match
         * - if a soft match is found, morph
         * - otherwise, prepend the new node before the current insertion point
         *
         * The two search algorithms terminate if competing node matches appear to outweigh what can be achieved
         * with the current node.  See findIdSetMatch() and findSoftMatch() for details.

         * This is the core algorithm for matching up children.  The idea is to use id sets to try to match up
         * nodes as faithfully as possible.  We greedily match, which allows us to keep the algorithm fast, but
         * by using id sets, we are able to better match up with content deeper in the DOM.
         *
         * Basic algorithm is, for each node in the new content:
         *
         * - if we have reached the end of the old parent, append the new content
         * - if the new content has an id set match with the current insertion point, morph
         * - search for an id set match
         * - if id set match found, morph
         * - otherwise search for a "soft" match
         * - if a soft match is found, morph
         * - otherwise, prepend the new node before the current insertion point
         *
         * The two search algorithms terminate if competing node matches appear to outweigh what can be achieved
         * with the current node.  See findIdSetMatch() and findSoftMatch() for details.

### Benchmark Overview

The benchmark titled **"Single Array & NamedNodeMap"** compares two approaches for iterating through HTML elements in a web page: one using a **NamedNodeMap** (which represents the attributes of an element) and the other using an **Array** created from that map.

### Test Options Compared

1. **NamedNodeMap Approach**
   - **Definition**: In this method, `NamedNodeMap` is utilized directly to access attributes of an HTML element.
   - **Code Snippet**: 
     ```javascript
     startEl.innerHTML = startElHTML
     window.Idiomorph.original.morph(startEl, endEl)
     ```
   - **Performance Result**: 
     - Executions per second: **304.24**

2. **Array Approach**
   - **Definition**: This method first converts the NamedNodeMap to an array and then iterates over it.
   - **Code Snippet**:
     ```javascript
     startEl.innerHTML = startElHTML
     window.Idiomorph.morph(startEl, endEl)
     ```
   - **Performance Result**: 
     - Executions per second: **283.98**

### Pros and Cons of Each Approach

**NamedNodeMap:**
- **Pros**:
  - Directly accesses attributes without the overhead of creating an additional array.
  - Potentially faster for scenarios where access patterns are simple and lightweight.
- **Cons**:
  - Iteration might be less flexible than using an array due to the nature of `NamedNodeMap`, which may not support all array methods directly.

**Array:**
- **Pros**:
  - Allows for the use of all array functions, including `.map()`, `.filter()`, and `.reduce()`, which may make the code cleaner and easier to understand for complex transformations.
  - More compatible with general JavaScript programming patterns, leading to easier integration with modern coding practices and utilities.
- **Cons**:
  - Involves a performance overhead due to the conversion from `NamedNodeMap` to an array. This may not be necessary if only simple attribute access is required.

### Other Considerations

- **Browser Compatibility**: Different browsers may implement these features (like `NamedNodeMap` and arrays) differently, which could lead to performance discrepancies outside of just the provided benchmarks.
- **Use Cases**: The choice between these approaches depends on the specific requirements of the application, such as the need for advanced array manipulation functions or simplicity in attribute access.
  
### Conclusion

In summary, for this particular benchmark, the NamedNodeMap approach slightly outperforms the Array approach in terms of execution speed. However, depending on the scenario and requirement for flexibility and operations on the attributes, the choice may vary.

#### Alternatives

1. **For-Of Loop**: Directly iterating over a `NamedNodeMap` using a `for-of` loop can be a balanced approach, maintaining performance while allowing for cleaner code.
2. **Object.entries()**: If you encapsulate attributes in an object, you can leverage `Object.entries()` for iteration, which allows for cleaner access patterns but may come with additional overhead compared to direct access methods.
3. **Using Libraries**: Libraries like jQuery simplify DOM manipulation, potentially negating the need for direct comparisons as shown in the benchmark through higher-level abstractions. However, this adds an external dependency and may involve a trade-off between simplicity and performance.

Single Array & NamedNodeMap (version: 1)

Comparing perf of iterating through a NamedNodeMap in syncNodeFrom vs an Array created from said map. In this variant, we only create the array for the element being modified.
