How to Create a JavaScript Object from a String

If you're new to JavaScript and trying to understand how to transform a string into an object, you've come to the right place! This guide will introduce you to a straightforward method to convert a textual representation of data into a structured object format that you can manipulate and use in your applications.

The Problem at Hand

Let's consider an example string that contains several pieces of information presented in a format that resembles a table. It might look something like this:

From this string, our goal is to create a JavaScript object that organizes this data in a more manageable way. The desired output object would look like this:

The Step-by-Step Solution

To accomplish this conversion, we will leverage JavaScript's split method to process the string. Here's how you can do it, broken down into clear steps.

Step 1: Define the String

First, define the string you want to convert:

Step 3: Split Each Line into Words

Now, we will split each line further into words using whitespace as a delimiter. This results in a two-dimensional array where each inner array represents a line of words:

Step 4: Construct the Object

Now it's time to construct our JavaScript object. We will initialize an empty object obj and fill it with the key-value pairs defined by our data:
