Benchmark: ternary vs Math.max vs if / else

Tests:

ternary
const delta = Math.round(); const duration = Math.round(); const result = delta < duration ? duration : delta;
if else
const delta = Math.round(); const duration = Math.round(); let result; if (delta < duration) { result = duration; } else { result = delta; }
Math.max
const delta = Math.round(); const duration = Math.round(); const result = Math.max(delta, duration);

Let's break down the provided benchmark and its test cases.

The benchmark is testing three different approaches to compare the values of two variables, `delta` and `duration`. The approaches are:

1. Ternary operator (`ternary`)
2. If-else statement (`if else`)
3. Math.max function (`Math.max`)

**Ternary Operator (ternary)**

The ternary operator is a concise way to write an if-else statement in one line of code:
```javascript
const result = delta < duration ? duration : delta;
```
This is equivalent to the following if-else statement:
```javascript
if (delta < duration) {
    result = duration;
} else {
    result = delta;
}
```
Pros:

* Concise and easy to read
* Can be more efficient since it avoids the overhead of an if-else statement

Cons:

* May not be as readable for complex conditions or when the condition is not obvious
* May not work in all situations, such as in older browsers that do not support ternary operators

**If-Else Statement (if else)**

The if-else statement is a more traditional way of writing conditional logic:
```javascript
let result;
if (delta < duration) {
    result = duration;
} else {
    result = delta;
}
```
Pros:

* Widely supported across all browsers and platforms
* Can be more readable for complex conditions or when the condition is not obvious

Cons:

* More verbose than the ternary operator
* May have slightly higher overhead due to the if-else statement

**Math.max Function (Math.max)**

The Math.max function can be used to find the maximum value between two numbers:
```javascript
const result = Math.max(delta, duration);
```
Pros:

* Concise and easy to read
* Widely supported across all browsers and platforms
* Can handle multiple values beyond just two inputs

Cons:

* May not be as efficient for small datasets since it involves a function call
* Returns the maximum value, which may not always be what you want (e.g., if you want the smaller value)

**Other Considerations**

When choosing between these approaches, consider the following factors:

* Performance: If you need optimal performance, the ternary operator might be a better choice. However, for most use cases, the difference in performance is unlikely to be noticeable.
* Readability: If readability is important, the if-else statement might be a better choice.
* Browser Support: All three approaches are widely supported across browsers and platforms.

**Library Usage**

There are no libraries used in these test cases. The functions and syntax are built-in JavaScript features.

**Special JS Features or Syntax**

None of the test cases use any special JavaScript features or syntax beyond what is described above (ternary operator, if-else statement, Math.max function).

**Alternatives**

Other alternatives to compare values could include:

* Using a switch statement instead of an if-else chain
* Using a binary search algorithm for large datasets
* Using a third-party library like Lodash or Ramda for more complex comparisons

Keep in mind that these alternatives may not be relevant for this specific benchmark, and the choice of approach depends on the specific use case and requirements.
