v0.26.x upgrade issue for iPad mini (ios 9.3) - Unable to load the library due to error

[FiveHundredMiles]

I upgraded my app to v0.26.1. But it doesn't work for iPad Mini (iOS 9.3).
Below is the error message:
Unexpected keyword 'const'. Const declarations are not supported in strict mode.

@FiveHundredMiles:

Do you have more information about where this problem occurs?

[FiveHundredMiles]

This is the line on the index.html
<script src="js/ramda.min.js"></script>

It (v0.26.1) works on my iPad. But it does not work on my (old) iPad mini.
The browser is Safari.
I rollbacked my code back to v0.25.x, and it worked - not loading issue.

Here is something that I found related to this error:
rails/webpacker#974

Thank you.

While I understand what the error is, the only usages I can find of const in, say, https://cdnjs.cloudflare.com/ajax/libs/ramda/0.26.1/ramda.js are in the examples in the comments. I'm not really sure where to look. How do you include Ramda? From a CDN? From an npm install? Something else?

[FiveHundredMiles]

I downloaded the zip from:
https://github.com/ramda/ramda/archive/v0.26.1.zip

I can see the const in both the ramda.js and ramda.min.js.
I can see the const on line number 2483 in ramda.js

Also, I would like to request a new function R.version? So, it will help resolve issues in the future.

[CrossEye]

Sure enough. I guess this is removed before the NPM package is published. I've never used this zip file myself.

If you're interested in creating a PR to fix this, please do. (It's not only pipeWith but also thunkify.) If not, I'll try to get to this soon.

I'm not so sure about version. Most users can simply get this from importing package.json. I don't know whether we want to include another non-function or a nullary function for this. I could certainly be convinced though.

[FiveHundredMiles]

To check the version, this is how jQuery does it:
jQuery().jquery
I'm not sure why they do it this way. Maybe we can do something similar.

The library should support all kind of environments or Use cases.
Also, package.json doesn't provide run-time check.

Just a thought. Thank you.

Also, package.json doesn't provide run-time check.

One can evaluate this expression at run-time:

require('ramda/package.json').version

It won't work in the browser, of course.
