Can you write a function that returns same result for both sum(2, 3) and sum(2)(3)?

I was trying currying in js but it works for sum(2)(3) and not on sum(2, 3)

const sum = a => b => a + b;

Where can I get more such challenges to practice and learn?

sum = (a,b)=>{
  if(b) {
    return a + b
  } else {
    return (d)=> {
       return a + d;
    }
  }
}

console.log(sum(3, 20))
console.log(sum(13)(20))
