    The Text.isElementContentWhitespace read-only property returns a Boolean flag indicating whether or not the text node's content consists solely of whitespace.


    b = textnode.isElementContentWhitespace;


    In the example below, we create a node with mixed display and whitespace characters and the attribute is false.

    var tn = document.createTextNode("Hello world");
    tn.isElementContentWhitespace; /* evaluates to false */

    For a node that is all whitespace characters, the isElementContentWhitespace evaluates to true.

    var ws = document.createTextNode("  \t \r\n   ")
    ws.isElementContentWhitespace; /* evaluates to true */
