Benchmark: AND logical vs ternary and IF

Script Preparation code:

var a = 10;
var b = 2;
var c = 0;

var nonZeroDivisorResult = 0;
var zeroDivisorResult = 0;

Tests:

IF Logic
if(b){ nonZeroDivisorResult = a/b; } else{ nonZeroDivisorResult = 0; } if(c){ zeroDivisorResult = a/c; } else{ zeroDivisorResult = 0; }
Ternary Logic
nonZeroDivisorResult = b ? a/b : 0; zeroDivisorResult = c ? a/c : 0;
AND Logic
nonZeroDivisorResult = b && a/b; zeroDivisorResult = c && a/c;

I'll break down the benchmark test cases and explain what's being tested, comparing options, pros and cons, and other considerations.

**Benchmark Test Cases:**

The test cases measure the performance of three different approaches to handle division by zero errors:

1. **IF Logic**: Uses an if-else statement to check if the divisor is non-zero before performing the division.
2. **Ternary Logic**: Utilizes a ternary operator to concisely express the same logic as IF Logic.
3. **AND Logic**: Employs the logical AND operator (`&&`) to combine two conditions: checking for divisibility by zero.

**Library Used:**

None of these approaches require any external libraries.

**JavaScript Features/Syntax Used:**

* Ternary operators (`?:`)
* Conditional expressions (not explicitly mentioned, but implied by the ternary logic)
* Logical AND operator (`&&`)

Now, let's dive into each approach:

### IF Logic

```javascript
if(b){ nonZeroDivisorResult = a/b; } else { nonZeroDivisorResult = 0; }
if(c){ zeroDivisorResult = a/c; } else { zeroDivisorResult = 0; }
```

Pros: Easy to read and understand, suitable for complex logic.

Cons: May lead to slower performance due to the overhead of conditional checks.

### Ternary Logic

```javascript
nonZeroDivisorResult = b ? a/b : 0;
zeroDivisorResult = c ? a/c : 0;
```

Pros:

* Concise and expressive, making it easier to understand and maintain.
* Often faster than IF Logic due to reduced overhead.

Cons: May be less readable for those unfamiliar with ternary operators.

### AND Logic

```javascript
nonZeroDivisorResult = b && a/b;
zeroDivisorResult = c && a/c;
```

Pros:

* Can lead to slightly faster performance, as it uses a single operation.
* More concise than IF Logic or Ternary Logic for simple cases.

Cons: May be less readable due to the use of logical AND, which can be unfamiliar to some developers. In this specific case, it's not significantly different from Ternary Logic in terms of readability.

**Other Alternatives:**

1. **Error Handling**: Instead of explicitly handling division by zero errors, you could throw an error and catch it elsewhere in the code.
2. **Zero-Handling Functions**: Some libraries offer functions specifically designed for handling zeros (e.g., `Math.abs()` or `Number.EPSILON`).
3. **Just-In-Time (JIT) Compilation**: In some cases, using a JIT compiler can optimize away the overhead of conditional checks.

Keep in mind that these alternatives might not be relevant to this specific benchmark test case and may have different performance implications in other contexts.

AND logical vs ternary and IF (version: 0)

In trying to avoid division by 0, a common alternative is to check if the divisor is 0 and if so then the result becomes 0 (with error logging taking place elsewhere).
