Examples
----------
These examples are intended to illustrate what jsPsych code and experiments look like. There is a larger set of example code in the [examples folder](/examples).
#### #1: Displaying instructions [(code)](https://github.com/jspsych/jsPsych/tree/master/examples/demos/demo_1.html)
<div display="flex">
<img src="https://user-images.githubusercontent.com/14092539/28126774-801ea42e-66f8-11e7-9b6a-c8bad0026bec.gif" align="right" width=50% />
<div markdown="1" style="width: 50%;">

```javascript
var trial = {
type: 'instructions',
pages: [
'Welcome to the experiment. Click next to begin.',
'<p>In this experiment, you will view a ' +
'series of images and answer questions.</p>' +
'<p>Answer with the keys "y" or "n".</p>',
'<p>Here is an example:</p>' +
'<img src="img/age/of2.jpg"></img>' +
'<p>Is this person OLD or YOUNG?</p>'
],
show_clickable_nav: true
}
jsPsych.init({
timeline: [trial],
});
```

To edit jsPsych code you'll need a programming-friendly text editor. Some free options are:
* [Atom](https://atom.io) (Windows, OSX, Linux)
* [Notepad++](http://notepad-plus-plus.org/) (Windows)
* [TextMate](http://macromates.com/) (OSX)
* [VSCode](https://code.visualstudio.com/) (Windows, OSX, Linux)
Once you've got a text editor that you like, create a new file in the experiment folder called `experiment.html`
