Compare two versions of an application using key expressions (task: compare the old and new version of YouTube)

To compare the old and new versions of YouTube using key phrases, you can highlight the main metrics and characteristics that reflect changes in functionality and user experience. For example:

• Interface: compare key UI elements such as button placement, menus, search.
• Performance: page load times, video playback speed.
• Functionality: presence of new features (e.g., viewing modes, recommendations).
• User interaction: changes in ways of liking, commenting, subscribing.

Examples of key phrases for comparison:

• "Main page load time" of the old version vs. the new.
• "Number of clicks to start a video".
• "Presence of autoplay feature".
• "Display of recommendations".

Thus, by using these key phrases, you can structure the comparison and identify improvements or regressions between versions.
