Tell us what’s happening:
Describe your issue in detail here.
My codes are producing the required results on freecodecamp and also on my local environment, but cases are failing.

Please check the screenshot.

Your code so far
function curry(f){
return function(a){
return function(b){
return f(a, b);
}
}
}
function addTogether(a, b) {
const arr = ;
arr.push(a);
arr.push(b);
// console.log(arr);
if(arr.length == 2){
if(typeof a === ‘number’ && typeof b === ‘number’){
return a + b;
} else {
return undefined;
}
} else if(arr.length == 1 && typeof arr[0] === undefined){
return undefined;
}
}
let curriedSum = curry(addTogether);
console.log(curriedSum(2)([3]));
console.log(curriedSum(5)(7));

@S827

function addTogether(a, b) {
  const arr = [];
  arr.push(a);
  arr.push(b);
  // console.log(arr);
  if(arr.length == 2){
    if(typeof a === 'number' && typeof b === 'number'){
      return a + b;
    } else {
      return undefined;
    }
  } else if(arr.length == 1 && typeof arr[0] === undefined){
    return undefined;
  } 
}

You are not handling the case where only one argument is passed here.

Thanks for pointing it out.
