Working with data in JavaScript often involves dealing with JSON (JavaScript Object Notation) format.
While JSON objects are relatively straightforward to handle, JSON arrays can be a bit trickier, especially when it comes to deserializing them. But fear not! This article will guide you through the process, providing clear explanations and practical examples to help you become a JSON array deserializing pro.
First, let’s quickly review what JSON arrays are. A JSON array is a collection of values enclosed in square brackets, with each value separated by a comma. These values can be strings, numbers, booleans, objects, or even other arrays. Here’s an example:
[

"color": "green"
