Type Alias MutableProperty<T, K>

MutableProperty: Omit<T, K> & { -readonly [P in K]: T[P] }

Make a specific property mutable (remove readonly).

Type Parameters

T
The object type
K extends keyof T
The key of the property to make mutable

Remarks

Removes the readonly modifier from a single property while leaving others unchanged. Useful for controlled mutability in type-level object transformations.

Example

type Obj = { readonly a: string; readonly b: number };
type Result = MutableProperty< Obj, 'a' >; // { a: string; readonly b: number }
