Internet Explorer bug: TypeError("Invalid attempt to spread non-iterable instance")
See original GitHub issueI’m receiving a type error when performing a df.where lookup (and I also see the same error for df.show. This is only on IE, doesn’t occur on any other browser.
The error I get in my console is:
SCRIPT5022: Exception thrown and not caught
File: 0.chunk.js, Line: 9670, Column: 3
but by stepping into the debugger call stack, I was able to narrow it down to an exception being thrown at: _nonIterableSpread [Line: 147, Col: 1], dataframe.js
You can reproduce this error using the following minimal example:
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
</head>
<script src="https://gmousse.github.io/dataframe-js/dist/dataframe.js"></script>
<script type="text/javascript">
var df = new dfjs.DataFrame([
{name: 'mark', age: '25'},
{name: 'steve', age: '35'},
{name: 'john', age: '35'}
]);
debugger;
</script>
</html>
And once in the debugger of IE, you will see there error for df.where and df.show(). Many other methods worked fine though, although I didn’t do an exhaustive check.
Looking forward to hearing your thoughts on what could be going on.

Thank you again @mbkupfer for the feedback and the PR. See you next time 😄.
@mbkupfer Hi !
Thank you too for your reporting !
You’re welcome to submit any PR in order to improve the library (for bug fixes, performance improvment, and new features)!
Don’t worry about reusables.js, I plan to refact (few part of codes such as reusables.js was realized few years ago when I was less pragmatic about coding 😄). I also plan add tutorials to make the contribution easier on the project.
I will be happy to see few contributors on the project, my available working time being limited on this library 😄.
