Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "To define the JavaScript function, the prototype function is used within the module."

A block of code is set as follows:

PageModule.prototype.calculate = function(number1,number2,op){
    if(op=="add"){
      return number1+number2;
    }    
    else if(op=="sub"){
      return number1-number2;
    }    
    else if(op=="mul"){
      return number1*number2;
    }    
    else if(op=="div"){
      return number1/number2;
    }
  }

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

AppModule.prototype.functionName = function (param1,param2){
    // write your logic here
    return "xyz";
  }

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

{
    "id": "0062v00001R0hMgAAJ",
    "success": true,
    "errors": []
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select the French radio button and see that the table columns will be rendered in French."
