Trying to build nest functions within nested functions

Question

working on a script and I thought dot notation would be a good way of building methods to use later on in the grander scheme of the script.

the original system would declare functions written as

memRead();
memReadGlobal();
memWrite();
memEtc();.......

but I wanted to change this to

mem.Read();
mem.Read.Global();

Here is an example

var mem = {
    Read: { 
        function() {
            console.log('Hello World')
        },
         Global: 
            function(key) {
                console.log('Goodbye World')
            },
    },
}

I can call mem.Global just fine, but I can't call mem.Read

I can declare mem.Read if I add another object like Local(mem.Read.Local), but I feel like writing local is redundant and would like to avoid that.

Is there a way to create a nested function like I describe above?

You are trying to do something that JavaScript object initializer syntax does not allow. — Pointy

You can do that, but not with an object initializer expression.

var mem = {
    Read() {
        console.log("Hello from Read");
    }
};
mem.Read.Global = function() {
    console.log("Hello from Global");
};

mem.Read();
mem.Read.Global();

Also, and this is of course merely an opinion, function names should start with a lower-case letter unless they're intended to be used as constructors.

Thanks @Pointy this worked well and I'll note to keep these functions lowercase :) Self taught and still learning. Thanks again :)
