Pure function, is that a functional programming lingo

[-] ThirdConsul@lemmy.zip 2 points 3 days ago

Pure function = no side effects, no internal state. If you run a pure function twice with the same input, it will give the same output.

Example of pure function

(a,b) => a+b

Example of inpure function

let c;

(a, b) => {
   c++;
   return a+b;
}
