How to convert a TS switch-case to ts-pattern

[st-clair-clarke]

Hello,
I have the following state management function that works:

	updateRepo(property: string, value: any, stateType: TStateType = 'domain') {
		store.update(
			write((state: IHistoryState) => {
				 switch (stateType) {
				 	case 'domain':
				 		state.domain[property] = value
				 		break
        
				 	case 'ui':
				 		state.ui[property] = value
				 		break
				 }
			}),
		)
	}

I am attempting to convert the switch-case above to ts-pattern as shown below (BUT IT DOES NOT DO ANYTHING)

	updateRepo(property: string, value: any, stateType: TStateType = 'domain') {
		store.update(
			write((state: IHistoryState) => {
				const output = match(stateType)
					.with('domain', () => (state.domain[property] = value))
					.with('ui', () => (state.ui[property] = value))
			}),
		)
	}

What am I doing incorrectly.
Cheers

Hi!

You need to end the expression with either .exhaustive() or .otherwise() to execute the code and get back the result. .with() is lazy so nothing happens until the pattern matching expression is ended
