Given the following pseudo-code for an anti-corruption layer translating legacy user data, what will be the output?

legacyUser = {"fullName": "Jane Doe", "age": 30}

function translateUser(legacy) {
  return {
    name: legacy.fullName,
    isAdult: legacy.age >= 18
  }
}

newUser = translateUser(legacyUser)
console.log(newUser)

A{"name": "Jane Doe", "isAdult": false}

B{"fullName": "Jane Doe", "isAdult": true}

C{"name": "Jane Doe", "isAdult": true}

D{"name": "Jane Doe"}

Step-by-Step Solution

Solution:

Step 1: Analyze the translation function
The function creates a new object with 'name' from 'fullName' and 'isAdult' as true if age >= 18.
Step 2: Apply the function to the legacy user
legacyUser has fullName 'Jane Doe' and age 30, so isAdult is true.
Final Answer:
{"name": "Jane Doe", "isAdult": true} -> Option C
Quick Check:
Translate fullName and check age >= 18 = true [OK]

Quick Trick: Check property mapping and age condition carefully [OK]

Common Mistakes:

Using legacy property names in output
Incorrectly evaluating age condition
Missing one of the output properties
