What is different for my program?

JavaScript

Tell us what’s happening:
i dont’t know what i am doing wrong. I’ve created an array, pushed the increasing number in the array and finally returned it with them.

  **Your code so far**



function rangeOfNumbers(startNum, endNum) {
if(startNum===endNum){
  return [endNum];
}
else{
  let a =[]
  a.push(rangeofNumber(startNum+1,endNum));
  return a;

}
};


//
//create arr
//if start===end, print [end]
//if start!=end
//array.push(start)
//foo(start+1)
//return arr

Why are you redefining an empty array every time you call this function?

This function always returns an array. The key idea of recursion is to call the function with a reduced input and use the output of that function call.
