We're going to replace this with a log value function and assign a parameter here with a type of string. So now if I console log this, I console log the city and I call the function with the name of the city, then I should be able to compile this correctly. So we'll run NPX TSC, then we'll run node generics and we'll get get Bend. Now, if I tried to pass in some sort of other value, like 600, you'll notice right away there's a problem here with a red squiggly underline. There's a problem here in the problems panel and there'll be a problem if I try to run it. So NPX TSC, we're getting that error because we're passing 600 when we should be passing a string. Now there's a way to make this function more generic with a value type parameter. Let me show you what I mean. If it doesn't matter what type is sent, as…
