Key Deliverables

• Remove all previous code-related files of the dummy-site. Retained the logo.png and rituraj-jain.jpg (rename and keep it organized in src/assets .
• add favicon.ico and a Preloader too.
• use SCSS (npm i scss previously known as dart-scss) to centralize repeatable CSS and Colors. It prevents rendering of the same code again and again. Using SCSS, throughout the website we will be able to use only a set of predefined colors provided in _color.scss. This will help maintain a color consistency and thus, it will set a "color theme" for the website
• Follow Proper File structure. Create a FILE-STRUCTURE.md. Implement boiler Plate code within each and every file.
• implement SEO using "react-helmet".
• App.jsx should redirect all invalid routes to 404 page.
• Header and Footer components should be imported in App.jsx such that Header and Footer will appear in all pages except the 404 page
• Implement Code splitting in App.jsx. Code-splitting enables bundling of different pages. Thus, when a user requests a particular page, only the code bundle required to load that page is downloaded. This increases the Load time of the webapp significantly 😍😍
