function overloading in javascript

function overloading in javascript refers to the ability to define multiple functions with the same name but with different numbers of parameters or parameter types. when you call an overloaded function, the javascript engine determines which version of the function to execute based on the number and types of arguments passed to it.

here's a step-by-step tutorial on how to achieve function overloading in javascript:

step 1: define a function with the same name but different number of parameters or parameter types

step 2: check the number of arguments passed and call the appropriate version of the function

in this example, we have defined two versions of the `add` function with different numbers of parameters. we then created a wrapper function `addnumbers` that checks the number of arguments passed and calls the appropriate version of the `add` function.

function overloading is not natively supported in javascript, so this is a common workaround to achieve the same result. it allows you to create functions that behave differently based on the arguments passed to them.

keep in mind that javascript is a dynamically typed language, so you need to be careful when using function overloading to ensure that the correct version of the function is called based on the arguments passed.
