Removing object properties with Lodash

Question

I have to remove unwanted object properties that do not match my model. How can I achieve it with Lodash?

My model is:

var model = {
   fname: null,
   lna

You can use _.omit() for emitting the key from a JSON array if you have fewer objects:

_.forEach(data, (d) => {
    _.omit(d, ['keyToEmit1', 'keyToEmit2'])
});

If you have more objects, you can use the reverse of it which is _.pick():

_.forEach(data, (d) => {
    _.pick(d, ['keyToPick1', 'keyToPick2'])
});
