What is Latency in web applications?

Latency in web applications refers to the measurable delay between a user's action, such as clicking a button or entering a command, and the subsequent response from the web application. This concept is crucial in web development as it directly impacts user experience; high latency can lead to frustration due to slow response times, while low latency results in a more seamless and interactive experience.

Understanding the nuances of latency helps developers optimize applications by minimizing delays, which can be achieved through various strategies, such as optimizing code, reducing server response times, or using Content Delivery Networks (CDNs). By focusing on reducing latency, developers aim to create applications that feel responsive and instantaneous to the user, enhancing overall satisfaction and engagement.
