How to add dynamically property for the parameter of React setState method-CodePudding

I use reactjs typescript on my project.

I use this lines of code :

if (reinitGridState) { 
   this.setState({
        isbusy: false,
        itemsList: data,
        colList: columns,
        gridState: this.initGridState,
        gridData: process(data, this.initGridState)
    });
} else {
    this.setState({
        isbusy: false,
        colList: columns,
        itemsList: data,
        gridData: process(data, this.state.gridState)
    });
}

And I want to remove the duplicate call of this.setState

I try this :

let newState = {
    isbusy: false,
    colList: columns,
    itemsList: data,
    gridData: process(data, this.state.gridState),
}

if (reinitGridState)
    newState.gridState = this.initGridState;

this.setState(newState);

But an error occured : Property 'gridState' does not exist on type '{ isbusy: boolean; colList: DisplayGridColumn[]; itemsList: any; gridData: DataResult; }

How can I specify a type for variable newState to add it dynamically the property gridState and satisfy the type wanted for setState ?

PS : I don't want to use this newState["gridState"] = this.initGridState;

Thank you

I believe you can resolve the error by defining the variable type, something like this (pseudocode).

interface MyState {
    isbusy: boolean,
    colList: ColumnType,
    itemsList: DataType,
    gridData: GridDataType,
    gridState?: GridStateType
}

// ...

let newState: MyState = {
    isbusy: false,
    colList: columns,
    itemsList: data,
    gridData: process(data, this.state.gridState),
}

if (reinitGridState)
    newState.gridState = this.initGridState;

this.setState(newState);

I didn't find a suitable solution to my problem, but I use this which is cleaner than the old colde for me :

            let newState = {
                isbusy: false,
                colList: columns,
                itemsList: data,
                gridData: process(data, this.state.gridState),
            }

            if (reinitGridState) {
                this.setState({
                    ...newState,
                    gridState: this.initGridState
                });
            } else {
                this.setState(newState);
            }
