javascript - Overriding interface property type defined in Typescript d.ts file

#short
#javascript

#typescript-typings
for example:
interface A {
property: number;
}

I want to change it in the typescript files that I write to
interface A {
property: Object;
}

or even this would work
interface B extends A {
property: Object;
}

Will this approach work? It didn't work when I tried on my system. Just want to confirm if it's even possible?
