Combine Two Broadcasters to Compare Values

We are both fetching a word from an API and type in text into an input box. We need a way to compare those two values to know if our guess is correct. We can do this by combining the two initial broadcasters And using operators to compare their values as each new value is pushed through. In this lesson, we write a combine operator that takes values from two broadcasters and pushes each value through in the form of an array with two values.
