Solution Review: Reverse a Stack

import Stack from './stack.js'
function insertAtBottom(stack, item) { // Creating a helper function
  // Base case
  if (stack.isEmpty() == true) {
    stack.push(item);
  }
  // Recursive case
  else {
    var temp = stack.pop();
    insertAtBottom(stack, item);
    stack.push(temp);
  } 
}
 
function reverse(testVariable) {
  // Recursive case
  if (testVariable.isEmpty() == false) {
    var temp = testVariable.pop();
    reverse(testVariable);
    insertAtBottom(testVariable, temp);
  }
}
myStack = new Stack(); 
myStack.push(2); 
myStack.push(3); 
myStack.push(5); 
myStack.push(8); // <---- 8 will be at the top of the stack because it was pushed last
console.log("Original Stack: ");
console.log(myStack.getStack());
reverse(myStack);
console.log("Reversed Stack: ");
console.log(myStack.getStack());
