How to omit specific properties from an object in JavaScript

Question

Is there a clean way to return a new object that omits certain properties that the original object contains without having to use something like lodash?

Answer 1

function omitKeys(obj, keys) {
        var target = {}; 

        for (var i in obj) { 
            if (keys.indexOf(i) >= 0) continue;
            if (!Object.prototype.hasOwnProperty.call(obj, i)) continue; 

            target[i] = obj[i]; 
        } 

        return target; 
    }
