Installing mathsteps is not straightforward about mathsteps

For the former, it is because "default parameters" in Javascript (an ES6 feature) were not enabled by default before node 6.0.0 (I think). So you need to be running at least node 6.

For the latter, what is the content of test.js? It does not seem to be a file at the root of the repository; did you create it?

Ah nevermind, I guess you copied the example script from the README into a test.js file. As far as I can tell there is either a mistake in the example or in the codebase. The property oldNode is null in the first step, however it is present in all the substeps. @evykassirer

After taking a look it seems it's due to some weirdness with Status.reset. When calling nodeStatus.reset() here it sets the oldNode property of the object that has just been pushed to steps to null.

I suspect this bug was not present at the time of this commit because it was manually cloning the node status. This might explain why the example does not reflect what's actually going on :-)

1. Yeah, you need at least node 6 for default parameters. I'll open an issue to add that to the documentation.

2. Okay yeah that's our fault. You have it installed correctly. We'll fix that bug and release a new version on npm and close this issue only once that's fixed

Thanks so much @kovzol for bringing both these issues up and @hmaurer for investigating 😄

Thank you for the prompt reply!

[evykassirer]

(fix made, reopening until I publish a new version of npm)

[evykassirer]

should be fixed now! please re-open this issue if you have any further problems with this.

thanks again for letting us know and @hmaurer and @Raibaz for fixing 😄
