Currying - Writing Sophisticated Functional Code
#FunctionalProgramming #Coding #Programming
In this video, we look at one of the representative techniques of functional programming, currying. Currying is a coding method that breaks down tasks that should be performed at once into multiple stages. To explain this, we use a function that makes a sandwich as an example, where a traditional function handles the three ingredients (bread, meat, vegetables) of a sandwich all at once, but Currying divides this process into each ingredient, or argument. This allows for the execution of functions in divided stages. By doing this, one advantage is that the original process can be diversely branched into multiple stages and branches for each ingredient. This video provides a detailed code example and explanation of this. In the next video, we're going to look at monads, one of the most challenging topics in functional programming.
