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:

[

  },
  [
    "grape",
    "strawberry"
  ]
]

This JSON array contains strings, an object, and another nested array.

Now, let’s dive into deserializing JSON arrays in JavaScript. Deserializing is the process of converting a JSON string into a JavaScript object or array. The built-in JSON.parse() method is your friend here:

const jsonString = '[1, 2, 3, 4, 5]'…
