import { registerWarnHandler } from '@ember/debug';

// next is not called, so no warnings get the default behavior
registerWarnHandler(() => {});

The handler function takes the following arguments:

• message - The message received from the warn call.
• options - An object passed in with the warn call containing additional information including:
• id - An id of the warning in the form of package-name.specific-warning.
• next - A function that calls into the previously registered handler.
