Adding Hello World JS to our HTML
Take challenge
1 question

Please watch this first.

Section 1: Chapter 1: Hello Javascript!

In this video we meet our instructor for the course, Mark Lassoff.  We also get introduced to the major server side and client side languages that are used on the web.  Mark also gives some background some background about HTML and CSS-- the other client side langauges that are used to create web sites.  Finally Mark gives a more detailed background of the Javascript programming language. 

9 slides

This set of slides have information about the course, the instructor and how to succeed in the course.  


In this video youi and Mark will create your first Javascript program.  Mark will explain what software you need to create Javascript (not much!) and how to go about creating yoiur first Javascript program and executing it in the browser.


In this video Mark introduces you to the three locations where you can embed Javascript code-- In the document , in the document and as an external attached file using the src attribute.  Mark will also provide a quick introduction to using Javascript functions which will be covered thoroughly later in the course.</p>

    Muy buen tutor

    Buen curso para iniciarse en javascript. El profesor es muy claro explicando cada tema y los ejercicios ayudan.

    • Ronando Long

    Course is dated and blurred, but gets the job done

    ​Course is now dated since it's using HTML4.1. Video is pixelated/blurred making it hard to read, resulting in some confusion as to what keys to type. For example, in the "function sayBye()" it is not clear that they are parenthesis and not curly brackets and Mark doesn't mention it as he's typing. However, I feel I got what I wanted out of the course, which was a quick guide in learning JS for beginners.

How JavaScript was Invented
in 10 Days

JavaScript is one of the most-used and most-valued programming languages in the world. It's been called the "assembly language" of the web. But it was invented in 10 days in 1995, when Netscape wanted a client-side programming language to run in Netscape's browser, Netscape Navigator.

If you're not familiar with web development, you probably still know that most webpages are made out of HTML. What you might not know is that HTML is not a programming language.

HTML stands for hyper text markup language, a mark-up language being a system of annotation. In other words, HTML is just a fancy way of formatting text and other elements. Like when you format a word document, once it's published you cannot change or reformat the contents of a website consisting solely of HTML -- in this sense it is "static." You can't set an HTML property to a variable, X, and then define X later.

With a programming language, on the other hand, you can assign, define, and manipulate variables. The trick to programming languages, in web development, is to have them interact with HTML. In a programming language designed for the web, you might define a variable X, and then have a program generate HTML with the present value of X as one of the properties.

Server-side scripting languages are programming languages that run on the server. Code written in a server-side language can grab a variable from a user's browser (like a cookie passed with the HTTP request) and then use that data to make more sophisticated or tailored HTML.

But server-side scripting isn't good for truly "responsive" designs. A client-side scripting program runs on the client side. In web terms that means in the browser of the person looking at a website. Client-side programs can change the website based on user behavior. If the user resizes a window, or mouses-over an element, or starts typing a search query, client-side code can change parts of the page in response. In order for this to work the browser needs to be built to run this code.

In 1995, Netscape already had one client-side language: Java. They had built support for applications written in Java -- developed by Sun Microsystems -- into their browser, Navigator. The trouble was in integrating Java applications into an overall web experience. Java apps run in a "sandboxed environment," isolated from the content of the page that hosts them. Netscape could have built support for Java as a scripting language, but they wanted a simpler language instead. This was partially because websites were often built by graphic designers, or amateur developers, with limited programming chops.

They cared about getting this scripting language together, but they also wanted it for their next release. To meet deadlines they gave a recently hired programmer 10 days to come up with an in-browser scripting solution.

That programmer was Brendan Eich. Netscape had lured Eich in on the promise of "do[ing] Scheme" (a programming language with a bit of a cult following) in the browser. Those dreams ended up not working out -- in fact, Eich quickly discovered he would have to invent a whole new language for Netscape.
As he's written, "The diktat from upper engineering management was that the language must ‘look like Java.' That ruled out Perl, Python, and Tcl, along with Scheme." He's also said, "I was under marketing orders to make it look like Java but not make it too big for its britches ... [it] needed to be a silly little brother language."

Though he tried to make it "look" like Java, Eich's invention was pretty syntactically different, borrowing more from more obscure languages like Scheme and Self. While it was in development, the language was called "Mocha." It was renamed "LiveScript" for its initial release. Then, Java became very popular before LiveScript did, so Netscape's marketing department renamed LiveScript "JavaScript" to piggyback on that cache.

Javascript and Web 2.0

Netscape didn't anticipate that people would start using JavaScript without Java. But they did. In fact, a lot of amateur web developers and pop-up ad designers started using it a lot of places they shouldn't have:

Pop-up ad (Edcollins)

For a long time, JavaScript was known to many as the language that made the web much more annoying. As Eich has commented, "JavaScript was cursed because it was mainly used for annoyances like little scrolling messages in the status bar at the bottom of your browser or flashing images."

Because JavaScript ran in the browser, its implementation was ultimately up to the designers of the various browsers. They built JavaScript engines to interpret and run the JavaScript, Eich's inaugural engine, which shipped with Netscape 2.0, and was called SpiderMonkey. The various engines ended up varying from browser to browser, sometimes a lot. IE3, for example, didn't support the document.images array. After several years of inconsistency, in the late 1990s, this led to the standardization of JavaScript as "EcmaScript" (established by a trade group, then called the European Computer Manufacturers Trade Association -- ECMA).

This kind of standardization was the most significant revision the language itself was ever going to get. As it was put in an article by the IEEE Computer Society, "Nothing built in 10 days is perfect, but once something is released into the wild, bugs or imperfections quickly become essential features and are nearly impossible to change."

But though JavaScript didn't change very much as a language, the tools to handle it -- including engines like SpiderMonkey, developer tools like in-browser debuggers, JavaScript libraries, and the Ecma standards -- developed a lot:

"... JavaScript had enough good stuff at the beginning to survive [...] it became fast enough and good enough in 2004 and 2005 to beget the Web 2.0 revolution."

The Browser Wars drove this innovation. As Microsoft, Mozilla, Google, and Apple competed over browser market share, one of the biggest battles to fight was improving the JavaScript runtime environment.

"[If you want to increase your market share,] it turns out that making a web browser that doesn't suck is Step 1," Meteor's Geoff Schmidt said at a conference in July 2015. "What was making web browsers suck? Javascript."

He went on to explain that this grievance drove the browser makers to make JavaScript the best they could: "The result is that JavaScript is now the best dynamic language runtime we've ever had. It far surpasses Ruby, Python, and PHP."

The Rise of JavaScript

One of the biggest innovations in web development was the rise of the framework. Frameworks are software environments -- which can consist of file structures, code libraries, and programming languages -- that are reused as the building blocks of novel projects. In many frameworks, including the very popular Ruby on Rails, JavaScript is the glue stitching together many different technologies.

Now, in some cases, these frameworks are being displaced by ones in which the majority of the code is written in JavaScript. Node.js is a JavaScript runtime environment invented as open-source technology in 2009. It's best use is for "fast, scalable network applications." With Node.js, the bulk of a project is typically written in JavaScript. Node.js has become so popular that it has surpassed Ruby on Rails as a Google search term:

Data: GoogleTrends

In addition to this, JavaScript is practically everywhere, now. In his talk at Devshop SF 2015, Geoff Schmidt called JavaScript the "only reasonable language for cross-platform app development." It's being used on browsers, on servers, on mobile, and there are even frameworks that compile other code into JavaScript for web purposes.

"Because of some special and unique historical circumstances," he concluded. "JavaScript has an enormous opportunity ahead of it. [...] JavaScript can change the world."

The JavaScript Community

Whether or not you believe Schmidt, his premises are inarguable. JavaScript is more or less ubiquitous across platforms, by design it's relatively easy to learn, it's incredibly fast, and -- Schmidt says -- it has a large community of people who know it or would like to know it.

That community is only getting bigger. Many of the JavaScript students on Udemy are people with a Computer Science background, expanding their skill set.

Because JavaScript has developed so much in the past fifteen years, there are a lot of people trying to take advantage of the powerful new applications of the language. It's also worth noting that Udemy is popular among people who studied graphic design, as well -- it's may be a programmer's programming language, but it's still not just a programmer's programming language.

What's more, the biggest professional demographic of JavaScript students on Udemy are CEO/Founders. Implying that whatever the next wave of technology looks like, there's a good chance JavaScript is going to play a big part in it.
