- In this C++ tutorial, you created a Visual Studio C++ console project and created your first C++ program, Hello World. Along the way, you learned how C++ code is built (preprocessor, compile, link), the basic structure of C++ applications, and a little bit of C++ history.
- A 'Hello World' program has been widely adopted as the introductory program for learning how to code. So, let's start functional programming by writing the same program. So, let's start functional programming by writing the same program.

“Hello World” project done in Visual Studio 2017 RC targeting Excel 2013 using Visual Studio Tools for Office(VSTO).
After the program is completed the rest of video gives some help when working with VSTO. How to clean up Excel ribbon using VSTO Power Tools for example.

This is my first youtube video so when I say app I mean addin. And VSTO is available in community editions as a download after Visual Studio Community is installed, missed that. Also, VSTO is available in community editions.

Hello, world! The tutorial that you’re reading is about core JavaScript, which is platform-independent. Further on, you will learn Node.JS and other platforms that use it. But, we need a working environment to run our scripts, and, just because this book is online, the browser is a good choice.

This part of the tutorial is about core JavaScript, the language itself.
But we need a working environment to run our scripts and, since this book is online, the browser is a good choice. We’ll keep the amount of browser-specific commands (like
alert
) to a minimum so that you don’t spend time on them if you plan to concentrate on another environment (like Node.js). We’ll focus on JavaScript in the browser in the next part of the tutorial.So first, let’s see how we attach a script to a webpage. For server-side environments (like Node.js), you can execute the script with a command like
'node my.js'
.The “script” tag
JavaScript programs can be inserted into any part of an HTML document with the help of the
<script>
Import shortcut android studio mac. tag.For instance:
Visual studio for mac 2017 debugger not working. You can run the example by clicking the “Play” button in the right-top corner of the box above.
The
<script>
tag contains JavaScript code which is automatically executed when the browser processes the tag.Modern markup
The
<script>
tag has a few attributes that are rarely used nowadays but can still be found in old code:![How to do hello world in python How to do hello world in python](/uploads/1/3/3/8/133848905/165981125.png)
type
attribute: <script type=…>
The old HTML standard, HTML4, required a script to have a
type
. Usually it was type='text/javascript'
. It’s not required anymore. Also, the modern HTML standard totally changed the meaning of this attribute. Now, it can be used for JavaScript modules. But that’s an advanced topic; we’ll talk about modules in another part of the tutorial.language
attribute: <script language=…>
This attribute was meant to show the language of the script. This attribute no longer makes sense because JavaScript is the default language. There is no need to use it.
In really ancient books and guides, you may find comments inside
<script>
tags, like this:This trick isn’t used in modern JavaScript. These comments hid JavaScript code from old browsers that didn’t know how to process the
<script>
tag. Since browsers released in the last 15 years don’t have this issue, this kind of comment can help you identify really old code.External scripts
If we have a lot of JavaScript code, we can put it into a separate file.

Script files are attached to HTML with the
src
attribute:Here,
/path/to/script.js
is an absolute path to the script from the site root. One can also provide a relative path from the current page. For instance, src='script.js'
would mean a file 'script.js'
in the current folder.We can give a full URL as well. For instance:
![How To Do Hello World In F# Virtual Studio For Mac How To Do Hello World In F# Virtual Studio For Mac](/uploads/1/3/3/8/133848905/944667757.jpg)
To attach several scripts, use multiple tags:
As a rule, only the simplest scripts are put into HTML. More complex ones reside in separate files.
The benefit of a separate file is that the browser will download it and store it in its cache.
Other pages that reference the same script will take it from the cache instead of downloading it, so the file is actually downloaded only once.
That reduces traffic and makes pages faster.
A single
<script>
tag can’t have both the src
attribute and code inside.How To Do Hello World In Python
This won’t work:
We must choose either an external
<script src='…'>
or a regular <script>
with code.The example above can be split into two scripts to work:
Summary
- We can use a
<script>
tag to add JavaScript code to a page. - The
type
andlanguage
attributes are not required. - A script in an external file can be inserted with
<script src='path/to/script.js'></script>
.
There is much more to learn about browser scripts and their interaction with the webpage. But let’s keep in mind that this part of the tutorial is devoted to the JavaScript language, so we shouldn’t distract ourselves with browser-specific implementations of it. We’ll be using the browser as a way to run JavaScript, which is very convenient for online reading, but only one of many.
