Task

Create an array called stars with the following star names:
- "Sirius";
- "Alpha Centauri";
- "Betelgeuse";
- "Polaris".
Log individual star names using different indices (0, 1, 2, and 3) using console.log


              123456
            
const stars = ___;

console.log("First element:", ___); // Output: Sirius
console.log("Second element:", ___); // Output: Alpha Centauri
console.log("Third element:", ___); // Output: Betelgeuse
console.log("Forth element:", ___); // Output: Polaris

Expected output:

Use square brackets [] to create an array.
Separate each element with the comma ,.
Use console.log() to log the value of the array element at the specified index.


              123456
            
const stars = ["Sirius", "Alpha Centauri", "Betelgeuse", "Polaris"];

console.log("First element:", stars[0]); // Output: Sirius
console.log("Second element:", stars[1]); // Output: Alpha Centauri
console.log("Third element:", stars[2]); // Output: Betelgeuse
console.log("Forth element:", stars[3]); // Output: Polaris
