In computer science, functional programming is a programming paradigm—a style of building the structure and elements of computer programs—that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. (WIKI)
Do you understand anything of it ? If not then I think we are then same! I also don’t understanding anything when I first read this meaning. What is mutable data ? or what is the meaning of this? Why it even used ?Let’s start will what is a mutable data ?
Mutable data means you can change this data. Like – suppose we’ve a variable a=5 and in later we change the value and put 10 in a by a=10.
Now do you know why we use functional programming ? Let me tell you the reasons
- Improve modularity
- Less code code redundancy
- More easier to solve complex problems
- More maintainable
- More Efficiency & some more
If you are using JS and used features like map or reduce. Do you know one thing?
You’re already using the functional programming!
