'Visual Studio Code | How to get Javascript class methods and variables to auto appear while coding in an HTML file

BACKGROUND

Just in case this helps you understand the problem. I came from coding in XCode with swift, back to Visual Studio Code to work on some web development stuff. I honestly may have been slightly spoiled, because while using XCode, when I'd try to call the method of a public class, once I'd pressed the . (Dot or Period) and a list of the classes methods and variables would appear, even if I wasn't on the document they were created on.

class SamplePage: UIViewController {
    
  collectPost(){
    var title = "Read It" }
}

Later I might call it this way - Don't swift with me now, so going off memory

collectPost().title`

Something like this, but when I'd type collectPost(). the options would appear.

QUESTION

Is there a way to see all possible methods and variables with a Javascript class, while coding in an HTML file between in Visual Studio Code?

Coding In Javascript, a whole list of the methods and variables pop up to choose from
