What's the meaning behind a JS function having functions itself?

Take the following code:

let myObject = {};
myObject.someFunction = function(){return 'sample function';};
myObject.someFunction.someOtherFunction = function(){return 'this somehow works';};

I can then run both myObject.someFunction() and myObject.someFunction.someOtherFunction() just fine.

What is the logic and implications behind this working? How is a function able to have methods?

Every function is an object in JS. – Bergi May 07 '18 at 13:15

*"How is a function able to have methods?"* Because functions are objects, and objects can have properties added to them, and properties can refer to functions (because...functions are objects :-) ). – T.J. Crowder May 07 '18 at 13:15
Re the dupetarget, your `myObject.someFunction` is the analogue of jQuery's `$`. – T.J. Crowder May 07 '18 at 13:16
