Separate views are stored in an ejs file. When the app starts, each file will be loaded, with the DOM elements hidden. Based on the state of the application, a specific view will be fadded in. Switching between views will use this principle.
Moved contents of index.ejs to landing.ejs to make it compatible with the new format. As a result, index.ejs is deprecated and will be removed once it is no longer needed for reference.
