Ruby - Metaprogramming FundamentalsWhat is the main purpose of Ruby's OpenStruct?ATo improve performance of Ruby programsBTo create objects with dynamic properties without defining a classCTo enforce strict typing on object propertiesDTo replace arrays with key-value pairsCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand what OpenStruct doesOpenStruct allows creating objects where you can add or change properties anytime without predefining a class.Step 2: Compare options with OpenStruct's purposeOptions A, C, and D do not describe OpenStruct's main use. It is not about performance, strict typing, or replacing arrays.Final Answer:To create objects with dynamic properties without defining a class -> Option BQuick Check:OpenStruct = dynamic properties [OK]Quick Trick: OpenStruct = flexible object with changeable properties [OK]Common Mistakes:Thinking OpenStruct improves speedConfusing OpenStruct with strict typingAssuming OpenStruct replaces arrays
