100 DataWeave Problems: Operators & Conditional Logic arithmetic, comparisons, logical operators, if/else, match/case, and default | Volume 3

100 Hands-On DataWeave Problems for Mastering Calculations, Comparisons & Decision-Making

Take your DataWeave skills to the next level with 100 practical problems focused on operators and conditional logic.

In real MuleSoft integrations, transformations often require more than simply mapping fields. You need to calculate values, compare data, evaluate multiple conditions, handle different scenarios, and dynamically decide what output to generate.

This ebook is designed to help you master those skills through 100 hands-on DataWeave problems with complete solutions.

📚 What's Inside

100 practical problems covering:

• Arithmetic Operators
• Comparison Operators
• Logical Operators
• Equality & Inequality
• if / else
• Nested Conditional Logic
• else if
• match/case
• default
• Conditional Field Mapping
• Dynamic Values
• Multiple Conditions
• Real-World Business Rules

🛠️ Practical Integration Scenarios

Solve problems based on situations such as:

• Calculate order totals
• Apply discounts based on conditions
• Determine customer categories
• Validate transaction amounts
• Compare API response values
• Calculate employee salaries and bonuses
• Handle different order statuses
• Dynamically assign values
• Apply multiple business rules
• Transform records based on conditions

💡 Every Problem Includes

Scenario → Input → Requirement → DataWeave Code → Output → Explanation

Each problem is designed to help you understand not only how the operator or conditional statement works, but also when to use it in a real MuleSoft integration.

🎯 What You'll Learn

By completing these 100 problems, you'll become confident with:

• Performing calculations using DataWeave
