When multiplenamespaces exist in the same scope, they undergo something calleddeclaration merging, where all their exports merge together. So thesenamespaces formed a single finaltsnamespace and everything just worked. TypeScript’s API did have a few "nested" namespaces which we had to maintain ...

Though in many cases, it is recommended to use A.merge(B) to merge two objects. The .merge method returns a new ZodObject instance, whereas A.and(B) returns a less useful ZodIntersection instance that lacks common object methods like pick and omit. const a = z.union([z.number(), z...
MergeDeep - Merge two objects or two arrays/tuples recursively into a new type. MergeExclusive - Create a type that has mutually exclusive keys. OverrideProperties - Override only existing properties of the given type. Similar to Merge, but enforces that the original type has the properties yo...

That brings us to the final stars of the feature:DisposableStackandAsyncDisposableStack. These objects are useful for doing both one-off clean-up, along with arbitrary amounts of cleanup. ADisposableStackis an object that has several methods for keeping track ofDisposableobjects, and can be give...
Using intersections to merge objects has two caveats. First, intersections are appliedrecursivelyon all object properties, so if some property is present on both typesit will be intersected too! This can yield unexpected results. Especially if the shared property contains types that do not overlap...
