Eliminated the redundant root route definition to avoid unnecessary rendering of the index page from the server side. Streamlined the client-side rendering of the mnemonic variable in the index.ejs file to always define the mnemonic constant. Enhances maintainability and reduces potential errors related to undefined variables.
