How can ı acces array items in node js


To access array items in Node.js, you can use the array index notation. The index notation allows you to access individual items in an array by specifying their position or index within the array.

Here’s an example of how you can access array items in Node.js:

// Define an array of numbers
const numbers = [1, 2, 3, 4, 5];

// Access the first item in the array
console.log(numbers[0]); // Output: 1

// Access the third item in the array
console.log(numbers[2]); // Output: 3

// Update the value of the fourth item in the array
numbers[3] = 10;

// Access the updated value of the fourth item in the array
console.log(numbers[3]); // Output: 10

In this example, we defined an array of numbers and accessed individual items using the index notation. We used the square brackets [] with the index of the item we want to access inside them. The first item in an array has an index of 0, the second item has an index of 1, and so on.

We also updated the value of an item in the array using the same index notation. By specifying the index of the item we want to update and assigning a new value to it, we changed the value of the item in the array.
