TS2540 — Cannot Assign to Readonly Property

Was verursacht diesen Fehler

The property is declared with the readonly modifier, which prevents reassignment after initialization. This applies to readonly class properties, Readonly<T> utility type, and const assertions.

So beheben Sie ihn

Do not modify readonly properties after initialization. Create a new object with the changed value if immutability is desired. Remove the readonly modifier if mutation is needed.

const obj = { name: 'A' } as const;
obj.name = 'B';
