    it helps in reducing set matched of elements to those that have descendant to the matched set of values

     

    1. <!doctype html>
    2. <html lang="en">
    3. <head>
    4.   <meta charset="utf-8">
    5.   <title>has demo</title>
    6.   <style>
    7.   .full {
    8.     border: 1px solid red;
    9.   }
    10.   </style>
    11.   <script src="https://code.jquery.com/jquery-1.10.2.js"></script>
    12. </head>
    13. <body>
    14.  
    15. <ul><li>Does the UL contain an LI?</li></ul>
    16.  
    17. <script>
    18. $( "ul" ).append( "<li>" +
    19.   ( $( "ul" ).has( "li" ).length ? "Yes" : "No" ) +
    20.   "</li>" );
    21. $( "ul" ).has( "li" ).addClass( "full" );
    22. </script>
    23.  
    24. </body>
    25. </html>
