Add properties to functions

Functions in JS are kind of an object (callable object). Hence, they can also store properties.

function func() {
    console.log('Hello World');
};

func.message = 'abc';

console.log(func()); // Hello World
console.log(func.message); // abc

That's a very short article:-D. Just to add, functions are first class objects so everything that is applicable to objects is also true for functions. The problem is how dev tools outputs differently for functions and objects. If you do console.log(func), you will see the function definition which leads us to believe that it cannot have properties. To see the function properties as object you can use console.dir(func).
