Is there a way to run queries via the feature layer api call?

    var livingAtlasLayer2 = new FeatureLayer({
        url: "https://services9.arcgis.com/RHVPKKiFTONKtxq3/arcgis/rest/services/USGS_Seismic_Data_v1/FeatureServer/query?outFields=*&where=Hours_Old%20%3C%20100"
    });

 

 So I am trying to run queries when creating a feature layer. So far, it just seems to ignore the query altogether and run the layer as normal. Is there a way to make this work using this method? I know normal api calls, this can work, depending on the source. 

My intent here is to control the data so that I only get the most recent data to show up.

What is the intent?  To filter the data being displayed on the map, or to query and retrieve a subset of the data that match your query parameters?

Filter data displayed on the Map
FeatureLayer.definitionExpression 

Rretrieve a subset of the data that match your query parameters
FeatureLayer.queryFeatures(...)
