Tests:

  • Lodash

     
    arr.map(function (element) {
        return _.omit(
            element,
            'card_last4',
            'card_type',
        );
    });

  • Native

    ​x
     
    arr.map(function (element) {
        const {
          card_last4,
          card_type,
          ...rest
        } = element;
    ​
        return rest;
    });

  • Manual omit

     
    arr.map(function (element) {
        return {
          type: element.type,
          subtype: element.subtype,
          card_exp_month: element.card_exp_month,
          card_exp_year: element.card_exp_year,
          card_country: element.card_country,
          something: element.something
        };
    });
