Why doesn't VSC show properties and methods of an object?

Question

Visual Studio Code

const soldier  = {
  health: 400,
  armor: 100,
  sayHello: function(){
    console.log('Hello');
  }
};

const jonh = Object.create(soldier);

For example, I create a jonh object. and when using an object in VSC, I want to see what properties, for example, are in this object, I write: john. I put an end to it but in the context menu that pops up the properties are not displayed. Why is that? maybe there is a plug-in, I did not find anything on the net.
