Building a web page can result in a large file size, but with the right techniques, it can be reduced. The New York Times is often cited as an example of a large web page, but even 11 megabytes is considered sizable. Micro Python, on the other hand, is much more efficient at around 170k. Combined with PiScript, it only takes half a megabyte to deliver to the browser. This is less than some hero images on websites. To optimize development, it is recommended to use a development environment and seek guidance from Damien, who has expertise in this area.
