### <a name="basic_methods-setdefaultoptions"></a>`setDefaultOptions`

```js
currentDefaultOptions = readlineSync.setDefaultOptions([newDefaultOptions])
```

Change the [Default Options](#basic_options) to the values of properties of `newDefaultOptions` Object.  
All it takes is to specify options that you want change, because unspecified options are not updated.

* Let the user choose an item from a list:

```js
var readlineSync = require('readline-sync'),
  animals = ['Lion', 'Elephant', 'Crocodile', 'Giraffe', 'Hippo'],
  index = readlineSync.keyInSelect(animals, 'Which animal?');
console.log('Ok, ' + animals[index] + ' goes to your room.');
```

### <a name="basic_methods-prompt"></a>`prompt`

```js
input = readlineSync.prompt([options])
```

Display a prompt-sign (see [`prompt`](#basic_options-prompt) option) to the user, and then return the input from the user after it has been typed and the Enter key was pressed.  
You can specify an `options` (see [Basic Options](#basic_options)) to control the behavior (e.g. refusing unexpected input, avoiding trimming white spaces, etc.).
