Benchmark: Readable vs Shorter

Script Preparation code:

var isValid = true;
var rand = Math.random() * 10;
var value1 = 'Toto';
var value2 = 'Titi';

Tests:

Readable
let output; if(isValid){ if(rand > 5){ ouput = "> 5"; } else { output = "< 5"; } } else { output = 'invalid'; } console.log(output);
Shorter
let output = !isValid ? 'invalid' : rand > 5 ? '> 5' : '< 5'; console.log(output);

Let's dive into the explanation of the provided benchmark.

**Benchmark Definition**

The benchmark is defined by two JavaScript microbenchmarks: "Readable" and "Shorter". The main difference between these two approaches lies in how they express conditional logic.

**Options Compared**

There are three options being compared:

1. **Readable**: This approach uses a more verbose, readable syntax to evaluate the condition. It's written as an if-else statement with multiple lines of code.
2. **Shorter**: This approach uses a more concise syntax to evaluate the condition. It's written as a single line of code using the ternary operator (`?:`).

**Pros and Cons**

### Readable Approach

Pros:

* Easier to read and understand, especially for developers who value readability.
* Can be easier to maintain and debug.

Cons:

* More verbose and takes up more space in the code.
* May be slower due to the extra overhead of evaluating multiple lines of code.

### Shorter Approach

Pros:

* More concise and takes up less space in the code.
* May be faster since it's a single line of code with fewer operations.

Cons:

* Can be harder to read and understand, especially for developers who value conciseness over readability.
* May be more error-prone due to the increased risk of typos or syntax errors.

**Library Used**

None

**Special JS Feature/Syntax**

The benchmark uses a feature called **Ternary Operators** (`?:`) which is a shorthand way of expressing simple if-else statements. The ternary operator takes three arguments: the condition, the value to return if true, and the value to return if false.

Example:
```javascript
let output = !isValid ? 'invalid' : rand > 5 ? '> 5' : '< 5';
```
This is equivalent to the following if-else statement:
```javascript
if (isValid) {
  if (rand > 5) {
    output = '> 5';
  } else {
    output = '< 5';
  }
} else {
  output = 'invalid';
}
```

**Other Alternatives**

Some other alternatives to the ternary operator include:

* Using `switch` statements for more complex logic.
* Using multiple `if` statements with early returns.
* Using `const` and `let` declarations with the `||` and `&&` operators.

However, these alternatives may not be as concise or readable as the ternary operator in this specific benchmark.

In summary, the Readable approach is more verbose but easier to read and maintain, while the Shorter approach is more concise but potentially harder to read and debug. The choice between these two approaches depends on personal preference and the specific use case.
