What is the difference between implementing Google maps with an API or embedding an iframe?

When implementing maps with an API versus embedding an iframe, the primary distinction lies in their impact on page loading speed and customization options.

Using an API is favored for its ability to optimize page loading times, making the overall user experience smoother and faster. Conversely, embedding an iframe is technically simpler, requiring less setup as users don't need to create API keys or manage usage limits.

However, the trade-off with iframe embedding is limited customization. With this method, we can only apply basic styling such as adjusting width, height, and borders. On the other hand, utilizing an API grants greater flexibility for customization, allowing for the application of custom colors to the map, creation of custom markers, and more detailed styling options.
