fn.js | JavaScript library built to encourage | Functional Programming library

You need to move the return next(); at the bottom of the Validate function inside the else:

It seems to be the assertion is not done on proper variable.

Need to assert on getLogger

Your first approach of writing test case is proper.

Add assertion something like this:

As I see (but not perfectly sure), GraalVM's Context.eval(Source source) method works the same way how JavaScript's eval() function does.

That can cause the problem, as JS eval always treats its input as a Script, not as a Module, and static imports are allowed only inside Modules.

You could try to use the dynamic await import('./testFn') syntax instead, which is allowed inside Scripts as well (if GraalVM supports it), but unfortunately I can't tell if it will work, and I don't know how to pass back asynchronous resources to Java.

You need to add the ./ to tell JavaScript The module you're looking for can be found in the following file path, relative to the current file. So you need to add ./ to say Look for sumfn.js in the current directory.

There seems to be some debate about whether Babel fully supports Glob patterns at the CLI level.

I managed to get it working with this ignore pattern:

Defining cars value under properties style is wrong, instead use:

Right, so it's kind of like you're serializing object data, but not class data. The variables persist, but the meta-stuff about the class (namely methods) aren't being preserved.

One solution might be serialijse.

serialijse is an simple persistence framework for JavaScript that overcomes two main limitation of JSON persistence:

• serialijse deals well with cyclic objects.
• serialijse preserve object class upon deserialization.

Their third examples demonstrates your case:

The main goal you're trying to do here is telling the browser its a new file when releasing a new version and we can do this fairly easily without having to force webpack to know what files are being used.

in your webpack config add this

The best answer here is to use a more reputable and feature-rich jQuery plugin. There are many (hundreds probably) jQuery slideshow plguins that are written very very well, are very efficient, and offer many features and hooks you can use to add your own custom functionality.

Here's 7 Great jQuery Slideshow Plugins

I'm not trying to be mean, but using these two jQuery plugins in tandem the way they are being used is very very inefficient, and the code in the plugins is already not great. It's not horrible, and it works, but there are much much better plugins available. Don't waste your own time re-inventing the wheel!

Ok - All that being said, I slapped some code into your plugins and updated your fiddle. I added this comment everywhere I added code // *added* so you can see what I did. Basically, the options for the jsshowoff plugin now has two extra settings. Just put your code there, and it will fire once before and once after each animation.
