Please tag a relevant language name apart from 'parameters' ☝
You can write in the Description if the title section isn't enough to type in completely.
As for your question, quoting from https://www.sololearn.com/learn/JavaScript/1147/
"If you pass more arguments than are defined, they will be assigned to an array called arguments. They can be used like this: arguments[0], arguments[1], etc."
Let's say you define a function with only 1 parameter ...
function myFunction(a)
{
// codes here
}
But you call the function passing more than 1 argument ...
myFunction("Hello", 123, 45.6, true);
Javascript will store arguments into an array named 'arguments'. And you can access it inside the function as follows ...
function myFunction(a)
{
console.log(arguments[0]);
// Hello
console.log(arguments[1]);
// 123
// and so on ...
}
