import {createSelector} from 'reselect';

const selector = createSelector(
  selectorA,
  selectorB,
  // (a, b) => doSomethignWith(a, b) // have to comment out to log it
  (a, b) => {
    var out = doSomethingWith(a, b)
    console.log('My Selector', out)
    return out
  }
)

After

import {createDebuggableSelector} from 'reselect-devtools';

const selector = createDebuggableSelector(
  depA,
  depB,
  (a, b) => doSomethingWith(a, b)
).debug('My Selector') // remove when done

  {
    inputs: [a, b],
    output: {...}
  }
