![]() So rather than having a function that looks like this: fakeFunction('param1', 'param2', 'param3') Rather, we’re talking about the process where a function takes multiple arguments one at a time. No, we’re not talking about the Indian spice. The ability to pass and return functions is done through one of three concepts: pure functions, higher-order functions, and currying. Immutability is one of functional programming’s best features. There are certain things that just simply don’t fit into the object-oriented way of thinking.įunctional programming is a style of writing code that involves a pattern of passing functions as arguments and the ability to return functions without causing side effects. ![]() But the truth is not everything is an object. When we start learning about code, we’re often told that everything is an object. You can mix and match from a range of patterns, and functional patterns are one of them. This means that it doesn’t conform to just one single pattern of coding. ![]() A Quick Primer on Functional Programmingīy design, JavaScript is multi-paradigm. So what is currying? How does it work? Why does it matter? And how do you apply it in your functions?īut before we get into all that, we need to first talk about functional programming. When you start to build more complex applications, you start looking into your toolbox for architecture and structural knowledge kit sets to help keep your team’s code sanity intact and ensure a certain level of clean code. It extends beyond the usual usage of functions and methods and starts to dive into the structural side of code. Currying is a topic that often sits in the more advanced user circles of JavaScript. ![]()
