Benchmark: Apply vs spread 23355235

Tests:

Apply
function getSum(...nums) { return nums.reduce((a, b) => a + b, 0); } function getAverage(...nums) { return getSum.apply(null, nums) / nums.length || 0; } console.log(getAverage(1, 2, 3, 4, 5));
Spread
function getSum(...nums) { return nums.reduce((a, b) => a + b, 0); } function getAverage(...nums) { return getSum(...nums) / nums.length || 0; } console.log(getAverage(1, 2, 3, 4, 5));

Let's dive into the world of JavaScript microbenchmarks.

The provided JSON represents a benchmark test case on MeasureThat.net, which allows users to compare the performance of different approaches in JavaScript. We'll explore what is being tested, the options being compared, their pros and cons, and other considerations.

**Benchmark Definition**

There are two benchmark definitions:

1. **Apply**: This approach uses the `apply()` method to call the `getAverage()` function with an array of numbers as arguments.
2. **Spread**: This approach uses the spread operator (`...`) to pass the array of numbers as separate arguments to the `getAverage()` function.

**Options being compared**

The two options are being compared in terms of performance, specifically:

* How many executions per second (ExecutionsPerSecond) can each approach achieve on a given machine.
* Which approach is faster overall (the one with higher ExecutionsPerSecond value).

**Pros and Cons of each approach:**

1. **Apply**:
	* Pros:
		+ Can be more concise and readable for some use cases.
		+ May work well when using functional programming patterns.
	* Cons:
		+ Can lead to slower performance due to the overhead of `apply()`.
		+ May not be as intuitive for developers unfamiliar with this method.
2. **Spread**:
	* Pros:
		+ Generally faster than `apply()` due to reduced function call overhead.
		+ More readable and maintainable code structure, especially in modern JavaScript.
	* Cons:
		+ Requires understanding of the spread operator syntax.
		+ May lead to longer function names or more complex code structures.

**Library:**

In this benchmark, there is no explicit library mentioned. However, the `reduce()` method used in both functions is a built-in JavaScript method that belongs to the ECMAScript standard.

**Special JS feature:**

There are no special JS features or syntax used in this benchmark. The focus is on comparing two approaches using regular JavaScript functions.

**Other alternatives:**

If you're interested in exploring alternative approaches, here are some ideas:

1. **Arrow functions**: You could use arrow functions instead of traditional functions to create a more concise version of the `getAverage()` function.
2. **Template literals**: Template literals can provide another way to format strings and may offer better performance in certain scenarios.
3. **Other reduction methods**: Depending on your specific requirements, you might consider using other reduction methods like `every()`, `some()`, or `find()`.

Keep in mind that the best approach will always depend on the specific use case, performance requirements, and personal coding preferences.
