Scope of eval

I have tried to eval some code inside a function and it seems to be running in the global scope and not that of the function.

var global = "a";
function test(){
     var local = "b";
     eval('print("global", global)');
     eval('print("local", local)');
}
test();

prints:

global a
Uncaught ReferenceError: "local" is not defined

Should eval() pick up the local variable?

Interesting, thanks. Looks like it should!

I've filed an issue for it at https://github.com/espruino/Espruino/issues/2164

Just to add, it looks like right now it sets the scope to whatever this is

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.
