How to Properly Map an Array of Strings into Buttons with Commas in React without Extra Spaces

If you are working with React and need to display an array of strings as a list of buttons separated by commas, you may run into formatting issues. For example, you might find that the output looks like this: One,Two,Three,Four instead of One, Two, Three, Four. This spacing issue arises when commas are added without spaces, which can confuse the user interface.

In this post, I'll explain how to properly map an array of strings into buttons separated by commas while ensuring there are no unwanted spaces. Let's dive into the solution!

The Problem

You might already have attempted mapping an array of strings into buttons like this:

This code correctly outputs a series of buttons but encounters issues with spacing, resulting in a lack of space after commas.

The Solution

To fix this issue, you must ensure that the comma and space are placed outside the <button> elements. Let's break the solution down into clear steps:

Step 1: Reorganize the Location of the Comma

Change your code from this:

By moving the comma placement outside of the button, you ensure it correctly separates the buttons without being included within them.

Step 2: Use Clean and Consistent Parameters

In your map function, the parameters can be directly simplified to avoid confusion:
