Enhancing function flexibility by supplying a multitude of parameters in Javascript

When working with Javascript functions, I aim to provide multiple parameters while ensuring clarity in terms of the passed values. Therefore, I have created the following function:

var callMe = function (param1, param2, param3) {
  console.log(param1 + ", " + param2 + ", " + param3) 
}

To call the method callMe(), I use the following syntax, where parameter values are initialized within the function call:

callMe(param1 = 1, param2 = 2, param3 = 3)

My intention is to ensure clarity when providing multiple parameters and avoid any confusion that may arise.

Is there a downside to this approach, or am I simply trying to overcomplicate things?

When you fail to declare your parameters beforehand using a var, you risk creating numerous global variables that can lead to a messy codebase. To avoid this, consider using a configuration object as an argument instead. While this approach may have its own limitations, it essentially achieves the same goal of passing arguments while ensuring a more organized structure that doesn't reinvent the wheel. Therefore...

var func = function (config) {
    console.log(config.param1 + ", " + config.param2 + ", " + config.param3);
}

func({
    param1: "Foo",
    param2: "Bar",
    param3: "Baz"
});
