Accessing Array Elements

In the previous exercise, we learned how to create an array. Now we will look at how to access individual elements in an array.

Each element in an array has an index, which is its position in the array. Array indices start at zero. This means that the first element has an index of 0, the second element has an index of 1, and so on.

Let's look at an example:

const newYearResolutions = ["Write a diary", "Attend a falconry course", "Learn to juggle"];

In this example, "Write a diary" is at index 0, "Attend a falconry course" is at index 1, and "Learn to juggle" is at index 2.

If we want to access the first element in the newYearResolutions array and print it, we use square brackets with the index of the element we want to access. For example:

console.log(newYearResolutions[0]);
// Prints: Write a diary

Similarly, we can access other elements in the array and print them:

console.log(newYearResolutions[1]); // Prints: Attend a falconry course
console.log(newYearResolutions[2]); // Prints: Learn to juggle

Or we can store the value in a variable:

firstResolution = newYearResolutions[0];
