Differences between CallExpr and MethodCallExpr in Javascript

[mrthankyou]

EDIT: I've discovered that I can look at the source code for MethodCallExpr and understand through the characteristic predicate what a method call expression means. Once I complete my research I'll post my answer below.

Hi,

I'm currently reviewing the docs and see that inside the CodeQL Javascript code there is both a CallExpr and a subtype MethodCallExpr. I know that CallExpr classes are used for direct calls and MethodCallExpr are used for indirect calls.

// Below is the documentation I found on CallExpr and MethodCallExpr:

// A CallExpr has the following examples:
//    f()
//    require('express')()
//    x.f()

// A MethodCallExpr has the following examples:
//    Object.create(null)
//    [1, 2, 3].forEach(alert);

Here's my question: what's the difference between the two classes?
