Benchmark: Nested tenary vs dictionary 222

Script Preparation code:

var random = Math.floor(Math.random() * 20);

Tests:

Tenary
const status = random === 0 ? -Math.PI: random === 1 ? Math.EPSILON: random === 2 ? 1: random === 3 ? 1: random === 4 ? 1: random === 5 ? 1: random === 6 ? 1: random === 7 ? 1: random === 8 ? 1: random === 9 ? 1: random === 18 ? 5: random === 19 ? 28: random === 20 ? 0: -1; console.log(status);
Dictionary
const test = { 0: -Math.PI, 1: Math.EPSILON, 2: 1, 3: 1, 4: 1, 5: 1, 6: 1, 7: 1, 8: 1, 9: 1, 18: 5, 19: 28, 20: 0, }; console.log(test[random] || -1);

Let's break down the provided benchmark and explain what is being tested.

**Benchmark Definition**

The benchmark is defined by two test cases:

1. **Nested Tenary**: This test case uses a nested ternary operator to evaluate an expression based on the value of `random`. The expression is: `random === 0 ? -Math.PI : random === 1 ? Math.EPSILON : random === 2 ? 1 : ...`.
2. **Dictionary**: This test case uses a dictionary (an object) to store values and evaluates the expression `test[random] || -1`. The `random` variable is generated using `Math.floor(Math.random() * 20)`.

**Options Compared**

The benchmark compares two approaches:

1. **Nested Ternary**: This approach uses nested ternary operators to evaluate the expression.
2. **Dictionary**: This approach uses a dictionary (an object) to store values and evaluates the expression using the `test[random] || -1` syntax.

**Pros and Cons of Each Approach**

* **Nested Ternary**:
	+ Pros: May be more concise and easier to read for simple expressions.
	+ Cons: Can be harder to maintain and modify for complex expressions, as it can become difficult to follow the nesting level.
* **Dictionary**:
	+ Pros: More readable and maintainable, especially for large datasets or complex expressions. The dictionary allows for easy addition or removal of values without modifying the expression.
	+ Cons: May require more code and be less concise than nested ternary.

**Library and Special JS Features**

There is no library used in this benchmark. However, it uses a JavaScript feature called **arrow functions**, which are not explicitly mentioned in the benchmark definition. Arrow functions are a shorthand way to define small functions, like the `test[random] || -1` syntax.

**Other Considerations**

When evaluating these two approaches, consider the following factors:

* **Readability**: Which approach is easier to understand and maintain?
* **Performance**: How fast does each approach execute?
* **Scalability**: Can either approach handle large datasets or complex expressions without performance issues?

**Alternatives**

If you're interested in exploring alternative approaches, here are a few options:

1. **Template literals**: Instead of nested ternary, you could use template literals to construct the expression.
2. **Math.max/min/avg functions**: You could use built-in Math functions like `max()`, `min()`, or `avg()` to evaluate the expression.
3. **Map/reduce functions**: If you need to process large datasets, consider using Map or Reduce functions.

These alternatives can offer different trade-offs in terms of readability, performance, and complexity.
