In the context of coding, what is meant by "code efficiency"?

Code efficiency refers to how well a piece of code utilizes system resources, such as CPU, memory, and time, to perform its tasks. Efficient code accomplishes its objectives while minimizing resource consumption, which is critical in creating applications that run quickly and smoothly, especially in environments where system resources are limited.

When considering how code behaves in terms of performance, it encompasses factors such as how quickly code executes, how much memory it consumes, and how effectively it handles various operations. This understanding is vital for developers as they optimize their programs to handle larger data sets or support more users without exhausting system capabilities.

Other aspects, like aesthetic quality or the number of lines of code, may contribute to code readability or maintainability, but they don't directly impact the efficiency with which the code performs its functions. Similarly, while complexity can involve considerations of efficiency, it does not substitute for the effectiveness of resource usage that defines true code efficiency.
