Ok. The guy writes about js fatigue. He appears to be chai.js maintainer. Ok, let's check it out. Oh, this is a library that lets you use three different styles to say the same thing

  chai.should();
  foo.should.be.a('string');

  var expect = chai.expect;
  expect(foo).to.be.a('string');

  var assert = chai.assert;
  assert.typeOf(foo, 'string');

Seriously? If this is not a major reason of js fatigue I don't know what is.
