👉 Else computing, also known as lazy evaluation or functional programming style, is a method of evaluating expressions where computations are not performed immediately but are instead deferred until their results are actually needed. This approach allows for more efficient memory usage and can lead to simpler, more modular code by avoiding unnecessary calculations. In functional programming languages like Haskell, expressions are evaluated only when their values are required, which can optimize performance and enable powerful abstractions such as infinite data structures and recursive algorithms without causing stack overflow errors. Essentially, else computing trades upfront computation for potential future use, enhancing both performance and code clarity.
