Conditional Expression Optimization in JavaScript

Code Analysis

The provided code appears to be a conditional expression likely used in a platform that supports logical operations like Power Automate or other scripting environments. The intent is to evaluate two main conditions related to the Trait_Code and MAIC_Plan and return specific values based on these conditions.

Problem Breakdown

1. The nested conditions are checking specific values for Trait_Code and MAIC_Plan.
2. The final condition is complex and nested, which might cause readability and maintainability issues.

Review Previous Attempts

No previous attempts are provided. Since the main challenge lies within readability, simplifying the nested conditions can help improve the clarity and maintainability of the code.

Solution

Proposed Changes:

1. Simplify nested or conditions using clear intermediate variables.
2. Ensure each condition is documented and validated correctly.

Code Development

Simplified Structure using Intermediate Variables

This solution leverages intermediate variables for clarity.

const traitCode = triggerBody()?.['Trait_Code'];
const maicPlan = triggerBody()?.['MAIC_Plan'];

// Define simple boolean expressions for readability
const isTraitCodeInGroup1 = ['NL', 'NZ'].includes(traitCode);
const isTraitCodeInGroup2 = ['MG', 'MB'].includes(traitCode);
const isMaicPlan_48_48_48 = (maicPlan === '48-48-48');
const isMaicPlan_90_90_90 = (maicPlan === '90-90-90');

// Main conditional logic
if ((isTraitCodeInGroup1 || isTraitCodeInGroup2) && isMaicPlan_48_48_48) {
  return 'B3';
}
if (isMaicPlan_48_48_48 || isMaicPlan_90_90_90) {
  return 'F2';
}

Comments and Documentation

// Retrieve values from the body of the trigger action
const traitCode = triggerBody()?.['Trait_Code'];
const maicPlan = triggerBody()?.['MAIC_Plan'];

// Check if traitCode matches any within group 1 (NL, NZ)
const isTraitCodeInGroup1 = ['NL', 'NZ'].includes(traitCode);

// Check if traitCode matches any within group 2 (MG, MB)
const isTraitCodeInGroup2 = ['MG', 'MB'].includes(traitCode);

// Check if MAIC_Plan value is '48-48-48'
const isMaicPlan_48_48_48 = (maicPlan === '48-48-48');

// Check if MAIC_Plan value is '90-90-90'
const isMaicPlan_90_90_90 = (maicPlan === '90-90-90');

// Evaluate first condition
if ((isTraitCodeInGroup1 || isTraitCodeInGroup2) && isMaicPlan_48_48_48) {
  return 'B3'; // Return 'B3' if conditions match
}

// Evaluate second condition if the first condition is not met
if (isMaicPlan_48_48_48 || isMaicPlan_90_90_90) {
  return 'F2'; // Return 'F2' if alternative conditions match
}

// Default case, if neither condition is met
return null; // or other appropriate default value

Code Usage Example

Example in a Real-World Scenario

const exampleTriggerBody = {
  'Trait_Code': 'NZ',
  'MAIC_Plan': '48-48-48'
};

const result = evaluateConditions(exampleTriggerBody);
console.log(result); // Expected output: 'B3'

function evaluateConditions(triggerBody) {
  const traitCode = triggerBody?.['Trait_Code'];
  const maicPlan = triggerBody?.['MAIC_Plan'];
  const isTraitCodeInGroup1 = ['NL', 'NZ'].includes(traitCode);
  const isTraitCodeInGroup2 = ['MG', 'MB'].includes(traitCode);
  const isMaicPlan_48_48_48 = (maicPlan === '48-48-48');
  const isMaicPlan_90_90_90 = (maicPlan === '90-90-90');

  if ((isTraitCodeInGroup1 || isTraitCodeInGroup2) && isMaicPlan_48_48_48) {
    return 'B3';
  }
  if (isMaicPlan_48_48_48 || isMaicPlan_90_90_90) {
    return 'F2';
  }
  return null;
}
