We can define a function to perform function composition using anonymous function syntax: f ∘ g = x -> f(g(x)) Note that this definition is equivalent to each of the following definitions: ∘(f, g) = x -> f(g(x)) or function ∘(f, g) x -> f(g(x)) end recalling that in Julia,...

One application of closures is to partially apply a function; that is, provide some arguments now and create a function that takes the remaining arguments. Currying is a specific form of partial application. Let's start with the simple function curry(f, x) that will provide the first argument to a ...

Functions are an important part of Julia programming. They can be defined directly within modules, in which case the functions are referred to as top-level. But functions can also be defined within other functions. Such functions are called "closures". Closures capture the variables in th...
