Lazy Properties

Lazy properties are a programming concept where the initialization of a property is deferred until it is first accessed, rather than being set when the object is created. This is used to optimize performance by avoiding unnecessary computations or resource allocations for properties that might not be used. It is commonly implemented in object-oriented and functional programming languages through specific language features or design patterns.

Also known as: Lazy Initialization, Lazy Loading, Deferred Initialization, Lazy Evaluation, Lazy Prop

Why learn Lazy Properties?

Developers should use lazy properties when dealing with expensive operations, such as database queries, file I/O, or complex calculations, where the property might not always be needed. This improves application startup time and memory usage by only performing the work when required. It is particularly useful in scenarios with optional features or configurations that are infrequently accessed.
