Javascript - how to declare namespace objects using new conventions

Question

I am a big fan of latest programming conventions and latest additions to programming languages. Recently I read in Google Guidelines that we should use const and let instead of var.

Now in my project I have namespace object variables (if that's what they are called, correct me please if I am wrong) like this

var myObj = {

    func1: {},
    func2: {}
};

var myOtherObj = {

    var1: 'foo',
    var2: 'bar'
};

How should I name these objects now using the new conventions, with const or with let? I am confused because I don't know if these big objects change over time, or not...

Answer 1

const doesn't prevent objects from changing (said otherwise it doesn't freeze them). It prevents the value of variables to change.

For example you can still do

const myObj = {

    func1: {},
    func2: {}
};

and then

myObj.fun3 = function(){...

What you can't do with a variable declared with const (but which doesn't seem to be your will) is

myObj = {};

Modules are usually declared with const.
