Function staticCheckPartial

This is a helper function to make sure a static type check is performed.

It may be required in some cases where TypeScript or the IDE fails to check the type of the argument and/or results in complex type error.

NOTE! IT DOES NOT PERFORM RUNTIME CHECKS.

You can use it like this:

interface Foo {
    name ?: string;
    age ?: number;
}

function createFoo (
    name ?: string,
    age ?: number
) : Foo {
    return {
        ...( name !== undefined ? staticCheckPartial<Foo>({name}) : {})
        ...( age !== undefined ? staticCheckPartial<Foo>({age}) : {})
    }
}

For example, this would end up as a static compile time error because there is no bar property:

  ...( age !== undefined ? staticCheckPartial<Foo>({bar: age}) : {})

Returns

The value which was provided as the argument untouched @PURE
