/**
|
|
* Lazy is a wrapper around a value that is computed lazily. It is useful for
|
|
* cases where the value is expensive to compute and the computation may not
|
|
* be needed at all.
|
|
*
|
|
* @param cb - The callback to lazily evaluate
|
|
* @typeParam Value - The type of the value
|
|
* @example
|
|
* ```ts
|
|
* const value = lazy(() => computeExpensiveValue());
|
|
* ```
