typescript object literal type definition

Question

I want to use typescript to define an object. The object can have any properties, but when accessing the properties, an error will be reported, showing Property "a" does not exist on type Object. Is there a way to define it? Such an object?

type Options = {
    data: Object
}
const v: Options = {
    data: {
        a: 1,
        b: 2
    }
}
v.data.a
// Property "a" does not exist on type Object

Answer 1

You defined data as Object, Object does not have a attribute

If you want to define an object with a key:value structure, do this

data: { [key: string]: any } 

Answer 2

Your data has no declared attributes and defaults to an empty object. Then you call a and it does not exist in the type declaration and an error is reported
