Question

Whenever I type console.log/console.dir on an object, one of the properties that always shows up is __proto__ which is the constructor.

is there any way to hide this?

Answer 1

Redefine console.log:

console.log = function (arg) {
    var tempObj;

    if (typeof arg === 'object' && !arg.length) {
        tempObj = JSON.parse(JSON.stringify(arg));
        tempObj.__proto__ = null;
        return tempObj;
    }

    return arg;
};

This won’t modify the original object which definitely needs to have __proto__.
