Javascript in salesforce lightning components

Hello,

I am wondering if there is any limitation in loading salesforce js files in the lightning component. I’ve a component with below lines, but it gives error while loading xdomain.js

cannot assign to read only property ‘query’ of object. #<object> throws at support/console/xdomain/30.0/xdomain.js : 12:19

<ltng:require scripts=”/support/console/38.0/integration.js” />
<ltng:require scripts=”/support/console/xdomain/30.0/xdomain.js” />

Thank you,

Sam
