In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Jasmine provides another global function called beforeEach."

A block of code is set as follows:

describe("Investment", function() {
  it("should be of a stock", function() {
    expect(investment.stock).toBe(stock);
  });
});

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

describe("Investment", function() {
  it("should be of a stock", function() {
    var investment = new Investment();
    expect(investment.stock).toBe(stock);
  });
});

Any command-line input or output is written as follows:

# npm install -g requirejs

New terms and important words are shown in bold.
