Exercise: Implement OP_ADD

Your task is to implement the OP_ADD function in the interactive code editor below. Use the provided template and follow the steps outlined in the comments.

Test your implementation by:

1. Pushing numbers onto the stack using the input field and "Push" button.
2. Clicking the "OP_ADD" button to execute your implementation.
3. Observing the result on the stack and the feedback message.

const OP_ADD = (stack) => {
  // Note: The stack is an array. You can use pop(), push(), and length.

// 1. Check if there are at least 2 elements in the stack
// 2. If not, return false
// 3. Pop the top two elements from the stack
// 4. Add them together
// 5. Push the result back onto the stack
// 6. Return true if successful, false if an error occurred

try {
// Implement OP_ADD here

    return true; // Operation successful

} catch (error) {
console.error("Error in OP_ADD:", error);
return false; // Operation failed
}
};

export default OP_ADD
;
