The journey begins by introducing the concept of a profit margin calculator. Then, I will walk you through the setup process for the project using Vite.js, a lightweight development server that allows you to quickly set up a new project with modern tools like React.js and TypeScript.

Moving forward, I will guide you through the process of building the UI for the profit margin calculator using Tailwind CSS, a popular CSS framework that makes it easy to style your components using pre-defined classes. You'll learn how to use Tailwind to create a responsive design that looks great on both desktop and mobile devices.

After the UI is in place, we will dives into the logic of calculating profit margins. I will walk you through the steps involved in calculating sale price, profit and gross margin and explain the formulas used to do so. You'll learn how to use TypeScript to add type safety to your code and catch errors early in the development process.

You will learn how to dynamically change the theme color based on user preference along with the dark mode. You will gain a solid understanding of how to implement dark mode and dynamic theme color using Tailwind CSS without any splash effect, making your website or application more accessible and user-friendly.

## **Why Vite.js?**
Vite is a build tool similar to Webpack. It can be used for React, Preact, Svelte, Vue, Vanilla JS, and LitElements. Vite is 100 times faster than Webpack and bundles your code with Rollup, pre-configured to output highly optimised static assets.

Vite has support for TypeScript projects as well. It provides a smooth and fast experience and makes your app run smoothly regardless of size.

Vite also supports hot module reload to reload a specific component on change during the development.

Unlike, React, where with the increasing app size, the performance slows down and takes a while to start or reload the dev server. On otherside, with vite, the performance doesn't change doesn't matter what the app size is..
