nested push-or-create-array in zustand and immer

Is there an easier way to accomplish this with zustand and immer, ie avoiding the conditional? this is inside a zustand

create

create

with immer middleware.

// StateType = { knownPaths: { [key: string]: string[] }; };

addPath(region, location) {
    set((state) => {
        if (region in state.knownPaths) {
            state.knownPaths[region].push(location);
        } else {
            state.knownPaths[region] = [location];
        }
    });
},

// StateType = { knownPaths: { [key: string]: string[] }; };

addPath(region, location) {
    set((state) => {
        if (region in state.knownPaths) {
            state.knownPaths[region].push(location);
        } else {
            state.knownPaths[region] = [location];
        }
    });
},
