9. What would happen, if you tried to assign result of void function to a variable?

Type void despite it's unique appliance is in TypeScript same type as any other - that's why there's no problem with assigning it to any variable, as long as it's type is not defined yet or it's void as well.

const voidFunc = (): void => {
	return;
}

const val = voidFunc();

const x: string = val; // Type 'void' is not assignable to type 'string'
