and we do not need to scroll up or down in IDE to find how and where it was initialized.

Example

// All setters (.setName() for example) returns reference to the this.
// In order to modify inner object like LineStyle or Pattern, to get this object (property) we should call getter to get object reference.
// Then modify it as shown below in Option 1 or you can use execute methods shown in Option 2.
import {Group} from '@int/geotoolkit/scene/Group';
import {Rect} from '@int/geotoolkit/util/Rect';
// Option 1
const group = new Group()
.setName('MyGroup')
.setBounds(new Rect(0, 0, 42, 16))
.enableClipping(true)
.setTag({'type': 'sometype'});

group.getLineStyle().setPattern('pattern');
return group;

// Options 2 ( using execute method )
return group
.execute(function () {
this.getLineStyle()
.setPattern("pattern");
});
