Lazy Evaluation

Lazy evaluation is a programming technique where computations are delayed until their results are actually needed. Instead of calculating everything upfront, the system postpones processing to save resources and improve efficiency. Think of it like preparing ingredients only when you're about to cook, rather than peeling and chopping everything in advance. This approach helps avoid unnecessary work, especially if some computations might not be used at all. It’s a way to optimize performance by doing only what’s necessary at the moment it’s needed.
