ES6
Haskell has been very influential for JavaScript

var numbers = [1, 2, 3, 4];
for (var i = 0; i < numbers.length; i++) {
numbers[i] = numbers[i] * 2;
}
console.log(numbers);
const numbers = [1, 2, 3, 4];
const multiplied = numbers
.map((number) => number * 2);
console.log(multiplied);
Until ES5
Starting with ES6
Why calling it .map?

"Haskell, at its core, is simple: it is just a polymorphic lambda calculus with lazy evaluation plus algebraic data types and type classes"

Category theory can be helpful in understanding Haskell's type system. There exists a "Haskell category", of which the objects are Haskell types, and the morphisms from types a to b are Haskell functions of type a -> b.
