How to Display a Bootstrap 4 Modal on Page Load without jQuery

Introduction

Have you ever wanted to show a Bootstrap modal right when your web page loads, but found yourself grappling with how to do it without using jQuery? You're not alone! It's a common challenge among developers who prefer to stick to pure JavaScript. In this guide, we'll explore a straightforward solution for displaying a modal in Bootstrap 4 upon page load—without jQuery.

Understanding the Problem

Bootstrap 4 modals are designed to be shown using JavaScript, often relying on jQuery for their functionality. Assembling the modal might seem easy; however, simply setting the display property to "block" won't display it as expected.
