.optional() makes the type optional? like using it with
z.boolean().default(false) makes it boolean | undefined4 Replies
you don't need to use
.optional when using .default @Whimsyoptional is like ?: T | undefined and default is like object destructuring with default. Note that "it" is different between the input type and output type for default since the input type is T | undefined and the output type is just T (which is the point of default)Yeah on the Output type that is.
.optional() allows undefined to be inputted, and outputs undefined for that value.
.default(value) allows undefined to be inputted, and outputs typeof value for that value.
So z.boolean().default(false makes the input type boolean | undefined and the output type boolean
while z.boolean.optional() makes both boolean | undefined.
You can see that here:

In the codebase it is even more explicitly stated: The output can never be undefined when using .default()yeah that's what i was asking
