## Example Usage

Below is a practical example illustrating how to use the  `addParam()`  function in an API call:

```javascript
# API call with addParam() 
        addParam(user, user_var) 
        addParam(password, password_var)
```

In this example, two parameters,  `user`  and  `password` , are being added to an API call. 
      The value of  `user`  is set to user_var and the value of  `password`  is set to password_var.
