  6. def \(fieldName: String): JsValue

    Return the property corresponding to the fieldName, supposing we have a JsObject.

    Return the property corresponding to the fieldName, supposing we have a JsObject.

    fieldName

    the name of the property to lookup

    returns

    the resulting JsValue. If the current node is not a JsObject or doesn't have the property, a JsUndefined will be returned.

  8. def apply(idx: Int): JsValue

    Return the element at a given index, supposing we have a JsArray.

    Return the element at a given index, supposing we have a JsArray.

    idx

    the index to lookup

    returns

    the resulting JsValue. If the current node is not a JsArray or the index is out of bounds, a JsUndefined will be returned.
