# Working with Object Params

Here's a different implementation of the `addTwoNumbers`

function:

This time the function accepts a `params`

object with `first`

and `second`

properties.

Similarly to last time, we're getting the "implicitly has an 'any' type" error.

## Challenge

Work out how to type `params`

as an object with a key of `first`

that is a number and a key of `second`

that is also a number.

## Transcript

We've got a similar problem here to what we had last time. We have a function argument which is giving us "Parameter 'params' implicitly has an 'any' type," except it's a little bit different because we've still got our addTwoNumbers function, except that we're parsing them in as an object into our function.

We somehow need to work out how to type this params as an object type with a key of first, which is a number and a key of second, which is also a number. That's your challenge.
