Writing a sum function in Typescript?

Issue

How can I create a one line function in typescript return like this:

sum(x)(y) -> x+y, e.g sums(2)(4) -> 6

Given that:

const result = sum(2)(4); // 6

console.log('Result:', result);

I have tried with a way like this:

    function sum(x: number, y: number) {
        return x + y;
    }

Solution

Like this

const sum = (x: number, y: number): number => x + y;

console.log("sum", sum(1,2))

const sumNested = (x: number) => (y: number): number => x + y;

console.log("sumNested", sumNested(3)(4))
