    total: 350,
    SN1: {

Answer 1

_.mapValues(object, v => _.isObject(v)? _.omit(v, 'reach'): v)

_.mapValues(object, [iteratee=_.identity])

Creates an object with the same keys as object and values generated by running each own enumerable string keyed property of object thru iteratee. The iteratee is invoked with three arguments: (value, key, object).

_.omit(object, [props])

creates an object composed of the own and inherited enumerable string keyed properties of object that are not omitted.
