the class AudioContext method decodeAudioData.

/**
 * The decodeAudioData() method of the BaseAudioContext Interface is used to asynchronously
 * decode audio file data contained in an ArrayBuffer. In this case the ArrayBuffer is
 * loaded from XMLHttpRequest and FileReader.
 * The decoded AudioBuffer is resampled to the AudioContext's sampling rate,
 * then passed to a callback or promise.
 * @param buffer An ArrayBuffer containing the audio data to be decoded, usually grabbed
 * from XMLHttpRequest, WindowOrWorkerGlobalScope.fetch() or FileReader
 * @param success A callback function to be invoked when the decoding successfully finishes.
 * The single argument to this callback is an AudioBuffer representing the decodedData
 * (the decoded PCM audio data). Usually you'll want to put the decoded data into
 * an AudioBufferSourceNode, from which it can be played and manipulated how you want.
 * @param error An optional error callback, to be invoked if an error occurs
 * when the audio data is being decoded.
 * @return the promise or null

the class HTMLOptionsCollection method add.

/**
 * Adds a new item to the option collection.
 *
 * <p><b><i>Implementation Note:</i></b> The specification for the JavaScript add() method
 * actually calls for the optional newIndex parameter to be an integer. However, the
 * newIndex parameter is specified as an Object here rather than an int because of the
 * way Rhino and HtmlUnit process optional parameters for the JavaScript method calls.
 * If the newIndex parameter were specified as an int, then the Undefined value for an
 * integer is specified as NaN (Not A Number, which is a Double value), but Rhino
 * translates this value into 0 (perhaps correctly?) when converting NaN into an int.
 * As a result, when the newIndex parameter is not specified, it is impossible to make
 * a distinction between a caller of the form add(someObject) and add (someObject, 0).
 * Since the behavior of these two call forms is different, the newIndex parameter is
 * specified as an Object. If the newIndex parameter is not specified by the actual
 * JavaScript code being run, then newIndex is of type net.sourceforge.htmlunit.corejs.javascript.Undefined.
 * If the newIndex parameter is specified, then it should be of type java.lang.Number and
 * can be converted into an integer value.</p>
 *
 * <p>This method will call the {@link #put(int, Scriptable, Object)} method for actually
 * adding the element to the collection.</p>
 *
 * <p>According to <a href="http://msdn.microsoft.com/en-us/library/ms535921.aspx">the
 * Microsoft DHTML reference page for the JavaScript add() method of the options collection</a>,
 * the index parameter is specified as follows:
 * <p>
 * <i>Optional. Integer that specifies the index position in the collection where the element is
 * placed. If no value is given, the method places the element at the end of the collection.</i>
 *
 * @param newOptionObject the DomNode to insert in the collection
 * @param beforeOptionObject An optional parameter which specifies the index position in the
 * collection where the element is placed. If no value is given, the method places
 * the element at the end of the collection.
 *
 * @see #put(int, Scriptable, Object)
