bookChallenge: Merging Objects and Adding Properties

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].

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:

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

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]); }
copy

Everything was clear?

How can we improve it?
