Data Access Tutorials

Introduction

Welcome to this introductory guide to data access techniques in JavaScript.

We'll explore fundamental concepts like data fetching, data manipulation, and asynchronous operations to help you build interactive applications.

Let's begin!

Data Fetching

Fetching data is the first step in many applications. It involves retrieving data from an external source, such as a server or database.

Different methods are available for fetching data: fetch, XMLHttpRequest, and AsyncDataURL

fetch is the modern way to make HTTP requests. It is easier to read and uses a single function to make multiple requests.

Data Manipulation

Once the data is retrieved, it's often necessary to manipulate it – transforming it or converting it into a more usable format.

map is used to create a new array by transforming each element in an existing array.

Asynchronous Operations

JavaScript often deals with asynchronous operations, meaning that an operation might not complete immediately.

For example, fetching data from a server can take some time. You should use async functions to ensure that your code runs without blocking while waiting for operations.
