How to run examples in the develop branch?

What command should we use to run an example in the develop branch?

What is wrong?

Examples are throwing errors in the develop branch.

Where does it happen?

In the develop branch.

How do we replicate the issue?

When I try to run any example in node, it’s throwing an error in the develop branch:

$ node examples/javascript/which-letter-simple.js 
.../brain.js/examples/javascript/which-letter-simple.js:1
(function (exports, require, module, __filename, __dirname) { import brain from '../../src';
                                                              ^^^^^^

$ node --version
v9.11.2

Expected behavior

It works fine in the master branch:

I was thinking of converting all those import statements to make it so we don’t have to build it. Thoughts?

Sure thing, I can convert all those imports to require’s.
