Did you actually type save() to save your code?

Also, I'd check that the button (or the pin it is connected to) isn't help down - if the button is held while Espruino boots then it won't load the saved code

I try save(); dont work.
Bottom is ok.
It is code for example.
var on = false;
setInterval(function() {
on = !on;
LED1.write(on);
}, 2000);
save();

What happens if you type BTN.read() on the left-hand side?

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.
