In both * scenarios, you chain together natural language assertions. * * // expect * var expect = require('chai').expect; * expect(foo).to.equal('bar'); * * // should * var should = require('chai').should(); * foo.should.equal('bar'); * * #### Differences * * The `expect` interface provides a function as a starting point for chaining * your language assertions. It works on both node.js and in the browser. * * The `should` interface extends `Object.prototype` to provide a single getter as * the starting point for your language assertions. Most browser don't like * extensions to `Object.prototype` so it is not recommended for browser use. * * #### Configuration * * By default, Chai does not show stack traces upon an AssertionError.
