# Arguments

* Created when the function is invoked.
* arguments are the input parameters passed to the function.
* It is an object that contains the index of the parameters as key and parameters are assigned as values against its index key.
* arguments values are accessed with arguments key word.
* arguments is not suggested to be used in the optimized codes instead use spread.

```javascript
EX 1:
function greet() {
    console.log(arguments);
}
greet(); // {}

EX 2:
function greetME(name) {
    console.log(arguments);
}
greetME("Vijay"); // { 0: "Vijay" }

EX 3: // using spread to access arguments as array
function greetings(...args) {
    console.log(args);
}
greetings("Hello", "Vijay") // ["Hello", "Vijay"]
```
