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;

Let's break down what's being tested in the provided JSON benchmark.

**Benchmark Definition:**

The benchmark is comparing three different approaches to perform arithmetic operations involving division:

1.  **Traditional IF-ELSE statement**: This approach checks if the divisor is zero and returns an error message or a special value (in this case, `nonZeroDivisorResult` is set to `0`) if the divisor is zero.
2.  **Ternary operator**: This approach uses a ternary operator to concisely evaluate the expression: if the condition is true, perform the division; otherwise, return an error message or a special value (`zeroDivisorResult`).
3.  **Logical AND operator**: This approach uses the logical AND operator (&&) to combine the two conditions and evaluate only one branch of the code.

**Options compared:**

The benchmark compares these three approaches:

*   Traditional IF-ELSE statement
*   Ternary operator
*   Logical AND operator

**Pros and Cons:**

1.  **Traditional IF-ELSE Statement:**
    *   Pros:
        *   Easy to read and understand for developers familiar with the syntax.
        *   Can be used to handle multiple conditions (not just division by zero).
    *   Cons:
        *   Requires more lines of code, which can increase execution time.
        *   May not be as concise or expressive as other approaches.
2.  **Ternary Operator:**
    *   Pros:
        *   Concise and expressive syntax for simple conditional statements.
        *   Can reduce the number of lines of code compared to traditional IF-ELSE.
    *   Cons:
        *   May not be immediately clear to developers unfamiliar with the syntax.
        *   Limited to single-line expressions; more complex logic may require multiple lines.
3.  **Logical AND Operator:**
    *   Pros:
        *   Can simplify conditional logic, especially when combined with other operators (e.g., &&).
        *   Reduces the number of conditions and operations compared to traditional IF-ELSE or ternary operator approaches.
    *   Cons:
        *   May require more setup and understanding of the operator's behavior (e.g., short-circuit evaluation).
        *   Can be less readable for developers unfamiliar with the syntax.

**Library/ Special JS Features:**

There are no libraries used in this benchmark. However, it does utilize special JavaScript features:

1.  **Ternary Operator**: A shorthand syntax for simple conditional statements.
2.  **Logical AND Operator**: Used to combine conditions and evaluate only one branch of the code.

**Other Alternatives:**

Other alternatives to these approaches could include:

*   Using a switch statement with a default case (for handling multiple conditions)
*   Employing a function or lambda expression to encapsulate the logic
*   Leveraging ES6's optional chaining operator (`?.`) for simplified conditional expressions

These alternative approaches might be more suitable for different scenarios, but they are not explicitly included in this benchmark.

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).
