**Benchmark Definition JSON**

The benchmark definition is empty, which means that no specific script or code needs to be executed beforehand. This suggests that the benchmark focuses on measuring the performance of a specific JavaScript operation or feature.

**Options Compared**

There are two test cases:

1. **Object.assign with spread syntax**: The first test case uses the spread operator (`...`) to merge an object `params` into another object `{ a: 2 }`. This option is compared to the traditional way of using `Object.assign()` method.
2. **Traditional Object.assign()**: The second test case uses the traditional `Object.assign()` method to merge the objects.

**Pros and Cons**

* **Spread Operator (Option 1)**:
	+ Pros: More concise and expressive, allowing for easier object merging.
	+ Cons: May have performance overhead due to the creation of a new array or object, depending on the browser implementation.
* **Traditional Object.assign() (Option 2)**:
	+ Pros: Well-established and widely supported, with a predictable performance profile.
	+ Cons: May require more code to achieve the same result as the spread operator.

**Library and Purpose**

There is no specific library mentioned in the benchmark definition. However, both `Object.assign()` methods rely on the ECMAScript 2015 (ES6) standard for spread syntax support.

**Special JS Feature or Syntax**

The test cases use the spread operator (`...`), which is a feature introduced in ES6. It allows for more concise and expressive object merging. The traditional `Object.assign()` method was available before ES6, but it's still widely supported.

**Other Alternatives**

If you're interested in alternative ways to merge objects in JavaScript, here are a few options:

* **Lodash.merge()**: A popular utility library that provides a safe and efficient way to merge objects.
* **JSON Merge Patch (JMP)**: A lightweight algorithm for merging two objects based on their JSON representations.

Keep in mind that these alternatives may have different performance profiles or trade-offs compared to the traditional `Object.assign()` method or the spread operator.
