Type Alias WritableValue<T>

WritableValue: Omit<T, "value"> & {
value: T extends { value: infer V } ? V : unknown;
}

Utility type that makes the 'value' property of a type writable.

This is useful for internal implementations that need to construct items with initially undefined values that are later populated.

Type Parameters

T
The type to make writable

Example

type ReadOnly = { readonly value: number };
type Writable = WritableValue<ReadOnly>;
// Result: { value: number }
