function sum(a) {
// Inner function to accumulate values
function inner(b) {
// If no arguments are passed, return the accumulated sum
if (b === undefined) {
return a;
}
// Otherwise, add the new value to the accumulated sum and return the inner function again
a += b;
return inner;
}
// Return the inner function to start the chain
return inner;
}

// Example usage
console.log(sum(1)(2)()); // 3
