Accessing Elements in an Array by Index

To access an element in an array, you can use square brackets ([]) with the index of the element you want to access. The index starts at 0 for the first element in the array and increments by 1 for each subsequent element.

Here’s an example of how to access elements in an array in JavaScript:

const fruits = ['apple', 'banana', 'orange', 'grape'];

// Access the first element
const firstFruit = fruits[0];
console.log(firstFruit); // Output: "apple"

// Access the third element
const thirdFruit = fruits[2];
console.log(thirdFruit); // Output: "orange"

In this example, we have an array of fruits and we use square brackets with the index of the element we want to access to assign the value of the first and third elements to variables.
