JS: this.constructor shorthand (calling static methods from non-static)

I have a JS class with utility static methods. Consider the following case:

class A{
    static util(){
        //do something
    }
    some_method(){
        //cumbersome
        this.constructor.util();
    }
};

class B extends A{
    static util(){
        //overrides super.util
        //does something different
    }
};

I'm using static method as a means to manage util functions, since it is easily overridable within an extended subclass. But the problem is that the way to access them is rather lengthy. Is there a shorthand, or a creative way to make it more manageable?

Instead of using static methods, I could resort to re-writing all the affected methods in the subclass and swap all the util functions, but that would be a shotgun surgery and will result in a very unmanageable code, so I want to avoid that as much as possible.

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
