How do you use lodash linking function- How do you chain functions using lodash?

problem ：

I have an object that looks like I have an object that looks like

var foundUser = {    charData: []}

which then I load an object from a database using mysql and then I call And then I use mysql Load an object from the database , Then I call

_.assignIn(foundUser, rows[0]);

But I get a few extra properties that I don't need (this isn't solvable by using select) But I got some extra attributes I didn't need （ Use select Can't solve the problem ）

So I call So I called

foundUser = _.omit(foundUser, ['blah']);

But it would be nice if I could just do But if only I could do it

_.assignIn(foundUser, rows[0]).omit(rows[0], ['blah']);

But that throws an error, am I doing it wrong or is there another way this can be done? But it leads to mistakes , Is it my fault or is there another way to do it ？
