It seems like a code that would bypass a crash in the program in case of an undefined value or null.<br />
If you remove it then in case there is such a null or undefined value you can't tell what the rest of the code would do.<br />
Unless of course you do! :)

Can anyone explain meaning of the code below and whether I can safely remove it?<br />
<br />
if (typeof (console) === &quot;undefined) {<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var console = {};<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var console.log = function() { };<br />

JavaScript function()

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

JavaScript

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.

Angular is a JavaScript open-source web application framework used to develop single-page applications. It aims to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–view-model (MVVM) architectures, along with components commonly used in rich Internet applications. Angular is the front-end part of the MEAN stack, together with Node.js runtime, Express.js backend framework and MongoDB database.
