In this video we will discuss the arguments object in JavaScript function definition.

Arguments is an Array object inside functions that contains the values of the arguments passed to that function.

The arguments object is a local variable available within all non-arrow functions. You can refer to a function's arguments inside that function by using its arguments object. It has entries for each argument the function was called with, with the first entry's index at 0.

You can use arguments.length to count how many arguments the function was called with. If you instead want to count how many parameters a function is declared to accept, inspect that function's length property.
