Course Overview

Welcome to this course Essential Secrets of JSON. ByteScout JSON is one of the most popular formats for serializing data into objects and is commonly used by many developers especially for talking to front-end web applications.

Now for any web application, one of the most important things is to be able to load data quickly and asynchronously without delaying page rendering. This capability is among the ones that raise the importance of JSON nowadays. Let's explore how JSON works and what we can do with JSON. Some of the major topics you will learn about in this course are as follows:

First, we will see what is JSON and why JSON appears. Then we will see why we should use JSON and how it differs from XML and its advantages over XML. We will dig deeper into the JSON specification and explore JSON in more detail like how to create JSON with an object inside or Array inside. We will convert a JSON string to an object and convert an object back to a string in chrome developer tools using JavaScript.

We'll see how to beautify JSON data using utilities provided by ByteScout and also see some gotchas or common mistakes generally developers make in JSON. We will read and manipulate JSON data using the PDF.co Web API provided by ByteScout. In this course, I will assume that you have some degree of technical experience in JavaScript and REST API.
