Challenge: Combine Objects with the Spread Operator

Task

Create a script that performs the following tasks:

Merge the properties of two objects, personInfo and jobInfo, and store them in a new object named fullInfo.
Add a new property to the fullInfo object named isRetired with a value of false.
Use a for...in loop to iterate through fullInfo, and log each property and its corresponding value in the format: [property]: [value].


              12345678910111213141516171819202122
            
const personInfo = {
  name: "Ferry",
  age: 62,
  city: "Caracas",
};

const jobInfo = {
  experience: 7,
  occupation: "Speech-Language Pathologist",
};

// Task 1: merge two objects
const fullInfo = {
  ...___,
  ___,
  ___: ___, // Task 2: add the property
};

// Task 3: log each property and its value
for (let key in ___) {
  console.log(`${___}:`, ___[key]);
}

Expected output:

name: Ferry
age: 62
city: Caracas
experience: 7
occupation: Speech-Language Pathologist
isRetired: false

Use the spread operator ({ ... }) to merge properties from personInfo and jobInfo into fullInfo.
After merging, add a new property to fullInfo.
Iterate through fullInfo using a for...in loop to log the properties and their values.


              1234567891011121314151617181920
            
const personInfo = {
  name: "Ferry",
  age: 62,
  city: "Caracas",
};

const jobInfo = {
  experience: 7,
  occupation: "Speech-Language Pathologist",
};

const fullInfo = {
  ...personInfo,
  ...jobInfo,
  isRetired: false,
};

for (let key in fullInfo) {
  console.log(`${key}:`, fullInfo[key]);
}
