Here you go: **ES5**


    var test = &#39;Hello World&#39;;
    if( test.indexOf(&#39;World&#39;) &gt;= 0){
      // Found world
    }

With **ES6** best way would be to use `includes` function to test if the string contains the looking work.

    const test = &#39;Hello World&#39;;
    if (test.includes(&#39;World&#39;)) { 
      // Found world
    }

Why do the following work?

    void foo() {
        cout &lt;&lt; &quot;Foo to you too!\n&quot;;
    };

    int main() {
        void (*p1_foo)() = foo;
        void (*p2_foo)() = *foo;
        void (*p3_foo)() = &amp;foo;
        void (*p4_foo)() = *&amp;foo;
        void (*p5_foo)() = &amp;*foo;
        void (*p6_foo)() = **foo;
        void (*p7_foo)() = **********************foo;

        (*p1_foo)();
        (*p2_foo)();
        (*p3_foo)();
        (*p4_foo)();
        (*p5_foo)();
        (*p6_foo)();
        (*p7_foo)();
    }

Is there any way that I can keep them in a static name?

Many analytic and tracking tools are requesting 1x1 GIF image (web bug, invisible for the user) for cross-domain event storing/processing.

&lt;b&gt;Why to serve this GIF image at all?&lt;/b&gt; Wouldn&#39;t it be &lt;b&gt;more efficient&lt;/b&gt; to simply return some error code such as *503 Service Temporary Unavailable* or empty file?

*Update:* To be more clear, I&#39;m asking why to serve GIF image data when all information required &lt;b&gt;has been already sent&lt;/b&gt; in request headers. The GIF image itself does not return any useful information.

How do I parse an URL with JavaScript (also with jQuery)?

For instance I have this in my string,

    url = &quot;http://example.com/form_image_edit.php?img_id=33&quot;

I want to get the value of `img_id`

I know I can do this easily with PHP with `parse_url()`, but I want to know how it is possible with JavaScript.

How can I use a for loop to dynamically create variables, and be returned.

    function createVariables()
    {
    for ( i=0; i&lt;=20; i++ )
        {
            var account = i;
            return var account + i;
        }
     }


The goal is to have the result below:

    var account1;
    var account2;
    var account3; and etc.....

Is there a convenience method to strip any leading or trailing spaces from a Java String?

Something like:

    String myString = &quot;  keep this  &quot;;
    String stripppedString = myString.strip();
    System.out.println(&quot;no spaces:&quot; + strippedString);

Result:

    no spaces:keep this

`myString.replace(&quot; &quot;,&quot;&quot;)` would replace the space between keep and this.

Strip Leading and Trailing Spaces From Java String

In the following code :

    #include &lt;iostream&gt;
    #include &lt;fstream&gt;
    #include &lt;string&gt;

    using namespace std;

    int main() {
        string x = &quot;This is C++.&quot;;
        ofstream of(&quot;d:/tester.txt&quot;);
        of &lt;&lt; x;
        of.close();

	
        ifstream read(&quot;d:/tester.txt&quot;);
        read &gt;&gt; x;
        cout &lt;&lt; x &lt;&lt; endl ;
    }

What is the best way to use the values stored in an Enum as String literals?
For example:

    public enum Modes {
        some-really-long-string,
        mode1,
        mode2,
        mode3
    }

Then later I could use `Mode.mode1` to return its string representation as `mode1`. Without having to keep calling `Mode.mode1.toString()`.

Please someone help me.

TypeError: coercing to Unicode: need string or buffer

I have two variables:  

    site1 = &quot;www.somesite.com&quot;;  
    site2 = &quot;www.somesite.com/&quot;;  

I want to do something like this

    function someFunction(site)
    {
        // If the var has a trailing slash (like site2), 
        // remove it and return the site without the trailing slash
        return no_trailing_slash_url;
    }

How do I do this?
