Question

So I have a property I want to make alias’s for.

var default_commands = {}
default_commands['foo'] = "bar";

Then I want a bunch of items to alias to “foo”

So if I wanted

default_commands['fu'] = default_commands['foo'];
default_commands['fuu'] = default_commands['foo'];

How could I do that so I don’t have to write that all out

I tried:

default_commands['fu','fuu'] = default_commands['foo'];

But that didn’t seem to work.

Answer 1

["fu", "fuu"].forEach(function (alias) {
    default_commands[alias] = default_commands.foo;
});

This won’t be an “alias” in the sense that word usually invokes:

default_commands.fu = 5;
console.log(default_commands.foo); // still "bar", not 5.

But it wasn’t clear what you meant in your question.
