How to Extract the Address from a Special String in JavaScript

JavaScript is a powerful tool for manipulating strings and extracting necessary information effortlessly. One common task developers encounter is isolating specific pieces of information from formatted strings. A typical scenario might involve needing to pull out an address from a string that also contains a person's name, their ID, and their position—like this one taken from a medical professional's information:

Understanding the Structure of the String

The string follows a consistent format:

Name

ID

Position

Address

Each of these components is separated by the delimiter -.

Given this structure, extracting each part becomes a matter of splitting the string and accessing the desired element. Below, we’ll break down the steps you need to take in order to isolate the address using JavaScript.

Solution: Step-by-Step Instructions

Step 1: Define the String

Before you can extract the address, you must define the string you will be working with in your code.

Step 2: Split the String

Utilize the split method to divide the string into an array of its components, using the specified delimiter.

This line takes the original string and transforms it into an array:

["JAMES SEVERA", "1679581110", "Physician/Psychiatry", "100 EAST BROADWAY, COUNCIL BLUFFS, IA 51503"]

Step 3: Access the Address

Now, you can easily access the address by selecting the last element of the array.
