How to make a deep copy of value

[mblandr]

So - question is simple. I need deep copy of value.
I try this create(v, (_)=>undefined)
I try this create(v, (_draft)=>draft)
but these are return original v, not copy
rawReturn(draft) return draft proxy.
So is there a way or I should use external libs for this?
Thanks

You can do this,

export function deepClone<T>(value: T): T {
  if (typeof structuredClone === 'function') {
    return structuredClone(value)
  }
  // fallback：You may use lodash/cloneDeep or your own implementation.
  // return cloneDeep(value)
  // or simple：
  return JSON.parse(JSON.stringify(value))
}

const nextState = create(state, (draft)=> {
  // some logic
  return rawReturn(deepClone(state));
});
