This function with fixed arguments can then be called from anywhere else in the code, and it will be as if we had called the original function with all of its arguments. Another way to think about it as like this. Normally when we call a function we have to pass all the arguments into it at the same exact time and place. What partial application allows us to do, is pass arguments to a function at different places in the code and then get the result once the function gets all of the arguments it needs. Now, partial application is also a very useful way to configure more general functions into more specific ones. In general, if there's a function that we use often in our code where one or more of the arguments that…
