That&#39;s probably a [requireJS](http://requirejs.org/) module definition

Check [here](http://requirejs.org/docs/api.html#define) for more details

&gt; RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.

define() is part of the AMD spec of js 

See:

Edit: Also see Claudio&#39;s answer below. Likely the more relevant explanation.


What is the difference between *syntax* and *semantics* in programming languages (like C, C++)?  

What is the difference between syntax and semantics in programming languages?

The title is pretty self-descriptive. I&#39;ve downloaded Qt Creator 2.7.0, and I am trying to compile some basic C++11 code:

    int my_array[5] = {1, 2, 3, 4, 5};
    for(int &amp;x : my_array)
    {
      x *= 2;
    }

I&#39;m receiving the following error:

    range based for loops are not allowed in c++ 98 mode

Yet, according to [this article][1] this version of Qt Creator supports C++11. So how do I enable it?

I see this being used all the time in JavaScript:

What is the `define` function?

How to go to a URL using jQuery or JavaScript. 

    &lt;a href=&quot;javascript:void(0)&quot;  onclick=&quot;javascript:goToURL()&quot;&gt;Go To URL&lt;/a&gt;

    function goToURL(url){
    // some code to go to url

    }

I don&#39;t want to use window.location as I want to invoke this link from a popup. 

New link should also open in a popup.  I also don&#39;t want to use Ajax. Just simulate href in JavaScript.

How to go to a URL using jQuery?

Regarding `$location.search`, the [docs][1] say,

&gt; Return search part (as object) of current url when called without any parameter.


  [1]: http://docs.angularjs.org/api/ng.$location

In my URL, my query string has a param `?test_user_bLzgB` without a value. Also `$location.search()` returns an object. How do I get the actual text?

Node.js servers are very efficient concerning I/O and large number of client connection. But why is node.js not suitable for heavy CPU apps in comparison to a traditional multithreading server?

What function will turn  `this contains       spaces`  into `this contains spaces` using javascript?

I&#39;ve tried the following, using similar SO questions, but could not get this to work.

    var string = &quot; this contains   spaces &quot;;
    
    newString = string.replace(/\s+/g,&#39;&#39;); // &quot;thiscontainsspaces&quot;
    newString = string.replace(/ +/g,&#39;&#39;);  //&quot;thiscontainsspaces&quot;

Is there a simple pure javascript way to accomplish this? 




How to remove the extra spaces in a string?

Im trying to assign a function inside a `struct`, so far I have this code:

    typedef struct client_t client_t, *pno;
    struct client_t
    {
        pid_t pid;
        char password[TAM_MAX]; // -&gt; 50 chars
        pno next;
        
        pno AddClient() 

        {
            /* code */
        }
    };
    
    int main()
    {
        client_t client;
    
        // code ..
    
        client.AddClient();
    }

&gt;     **Error**: *client.h:24:2: error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘{’ token.*

Which is the correct way to do it ?


C - function inside struct

I am working with a bash script and I want to execute a function to print a return value:
   

    function fun1(){
      return 34
    }
    function fun2(){
      local res=$(fun1)
      echo $res
    }

When I execute `fun2`, it does not print &quot;34&quot;. Why is this the case?

Return value in a Bash function

I created this function in Python 2.7 with `ipython`:

    def _(v):
        return v

later if I call `_(somevalue)`, I get `_ = somevalue`.

    in[3]: _(3)
    out[3]: 3
    in[4]: print _
    out[4]: 3

The function has disappeared! If I call `_(4)` I get:

```none
TypeError: &#39;int&#39; object is not callable
```

Why? What&#39;s wrong with this function?


Assigning a value to single underscore _ in Python/IPython interpreter

I have this object:

    var data = {&quot;id&quot;: 1, &quot;second&quot;: &quot;abcd&quot;};

These are values from a form. I am passing this to a function for verification.

If the above properties exist we can get their values with `data[&quot;id&quot;]` and `data[&quot;second&quot;]`, but sometimes, based on other values, the properties can be different.

How can I get values from `data` independent of property names?


Get values from an object in JavaScript

I have this function that calls itself:

    def get_input():
        my_var = input(&#39;Enter &quot;a&quot; or &quot;b&quot;: &#39;)
    
        if my_var != &quot;a&quot; and my_var != &quot;b&quot;:
            print(&#39;You didn\&#39;t type &quot;a&quot; or &quot;b&quot;. Try again.&#39;)
            get_input()
        else:
            return my_var

    print(&#39;got input:&#39;, get_input())

Now, if I input just &quot;a&quot; or &quot;b&quot;, everything works fine:

&lt;!-- language: none --&gt;

    Type &quot;a&quot; or &quot;b&quot;: a
    got input: a

But, if I type something else and then &quot;a&quot; or &quot;b&quot;, I get this:

&lt;!-- language: none --&gt;

    Type &quot;a&quot; or &quot;b&quot;: purple
    You didn&#39;t type &quot;a&quot; or &quot;b&quot;. Try again.
    Type &quot;a&quot; or &quot;b&quot;: a
    got input: None

I don&#39;t know why `get_input()` is returning `None` since it should only return `my_var`. Where is this `None` coming from and how do I fix my function?
