Task

You are given an object representing copper. Your task is to iterate through the properties of the copper object using the for...in loop. For each property, you should log both the property name and its value to the console.

  • Use the for...in loop to iterate through the properties of the copper object.
  • For each property, log a message to the console in the format: "Property: [property name], Value: [property value]".

const copper = {
  symbol: "Cu",
  atomicNumber: 29,
  meltingPoint: "1984.32 °F",
  appearance: "Red-orange metallic luster",
};

___ (let key ___ copper) {
  ___(`Property: ${___}, Value: ${___[___]}`);
}
copy

Expected output:

Property: symbol, Value: Cu
Property: atomicNumber, Value: 29
Property: meltingPoint, Value: 1984.32 °F
Property: appearance, Value: Red-orange metallic luster
  1. To iterate through the object properties, use the for...in loop. Start with for (let key in copper) { ... }.
  2. Inside the loop, access the property value using copper[key].
  3. Use console.log() to print the messages in the required format.

const copper = {
  symbol: "Cu",
  atomicNumber: 29,
  meltingPoint: "1984.32 °F",
  appearance: "Red-orange metallic luster",
};

for (let key in copper) {
  console.log(`Property: ${key}, Value: ${copper[key]}`);
}
copy
