Nice work

// Example 3
function sayHelloToUser(user) {
console.log(`Hello ${user}`);
console.log(`Hello ${user}`);
}

sayHelloToUser();


// Example 4
let arr = [1,2,3];
console.log(arr[3]);
let letters = [1, 2, 3];

The logic looks good to me 👍
Something to keep in mind: it's a good idea to use let or const when declaring a variable (like temperatures, city, information_string in your example.)

for (city of cities) {
temperature = temperatureService(city);
information_string = `The temperature in ${city} is ${temperature} degrees`;
temperatures.push(information_string);
}
return temperatures;
}

const cities = [
"London",
"Paris",
"Barcelona",
"Dubai",
"Mumbai",
"Sao Paulo",
"Lagos",
];

console.log(getTemperatureReport(cities));

This looks almost perfect to me!
Again, just remember to use let or const when declaring a variable 😄
