You can create an array of objects in JavaScript, where each object represents a city with its properties, including temperature. Here's how you can do it:

javascript
 
 
Copy code
const cities = [
    { name: "New York", country: "USA", temperature: 75 },
    { name: "Tokyo", country: "Japan", temperature: 80 },
    { name: "Paris", country: "France", temperature: 70 }
];

cities.forEach(city => {
    console.log(`The temperature in ${city.name} is ${city.temperature}°F`);
});

In this example, we have an array called cities containing three city objects. Each city object has a name, a country, and a temperature property. The forEach method is used to loop through each city in the array and log the temperature to the console. You can modify the properties as needed.

javascript
 
 
Copy code
// Create an array of 3 cities
const cities = ['New York', 'Tokyo', 'London'];

// Create an object with temperatures for each city
const temperatures = {
  'New York': 20,
  'Tokyo': 25,
  'London': 18
};

// Loop through the cities and console log each city temperature
cities.forEach(city => {
  console.log(`${city}: ${temperatures[city]} degrees Celsius`);
});

This code creates an array of 3 cities and an object with their respective temperatures. It then loops through the cities array and logs each city's temperature to the console.

javascript
 
 
Copy code
// Define the properties of a city
const paris = {
  name: "Paris",
  population: 2.2,
  country: "France",
  temperature: 19
};

// Create an array of 3 cities with the same properties as Paris
const cities = [
  {
    name: "New York",
    population: 8.3,
    country: "USA",
    temperature: 24
  },
  {
    name: "Tokyo",
    population: 37.4,
    country: "Japan",
    temperature: 26
  },
  {
    name: "Sydney",
    population: 5.3,
    country: "Australia",
    temperature: 21
  }
];

// Console log each city temperature
cities.forEach(city => console.log(city.temperature));

Note: This code creates an array of three different cities with the same properties as Paris, console logs each of their temperatures, and logs them to the console. If you need to add more cities, simply copy the same properties and add a new object to the cities array.

javascript
 
 
Copy code
// create an array of 3 cities with temperature property
const cities = [
  { name: 'New York', temperature: 20 },
  { name: 'Paris', temperature: 18 },
  { name: 'Tokyo', temperature: 26 }
];

// console log each city temperature
cities.forEach(city => {
  console.log(`${city.name} temperature is ${city.temperature}°C`);
});

This code creates an array of 3 cities with a temperature property, one for each city. Then, it loops over the cities array using the forEach method to log each city's temperature using string interpolation.

javascript
 
 
Copy code
// We can create an array of objects where each object contains information about a city, and one of those properties could be temperature. Here's an example:

let cities = [
  {name: 'Paris', country: 'France', population: '2.141 million', temperature: '17°C'},
  {name: 'London', country: 'United Kingdom', population: '8.9 million', temperature: '15°C'},
  {name: 'Berlin', country: 'Germany', population: '3.77 million', temperature: '12°C'}
];

// We can then loop through the array and log the temperature of each city:
cities.forEach(city => {
  console.log(city.temperature);
});

This will output:

code
 
 
Copy code
17°C
15°C
12°C

Note that the values for each city (other than Paris) are hypothetical and taken just as an example.

The following code creates an array containing 3 Australian city names and logs each name:

javascript
 
 
Copy code
var australiaCities = ['Sydney', 'Melbourne', 'Brisbane'];

australiaCities.forEach(city => {
  console.log(city);
});

You can create a loop function in Java using an array of cities using a for loop.

java
 
 
Copy code
// Initialise the array
String[] cities = {"London", "New York", "Tokyo", "Paris"};

// Use a for loop to iterate through the array
for(int i = 0; i< cities.length; i++){
    System.out.println(cities[i]);
}
