//Basic Mathematical Operations
// Your task is to create a function that does four basic mathematical operations.

// The function should take three arguments - operation(string/char), value1(number), value2(number).
// The function should return result of numbers after applying the chosen operation.

// Examples(Operator, value1, value2) --> output
// ('+', 4, 7) --> 11
// ('-', 15, 18) --> -3
// ('*', 5, 5) --> 25
// ('/', 49, 7) --> 7

//My Answer
function basicOp(operation, value1, value2) {
  if (operation === "+") {
    return value1 + value2;
  } else if (operation === "-") {
    return value1 - value2;
  } else if (operation === "*") {
    return value1 * value2;
  } else if (operation === "/") {
    return value1 / value2;
  } else {
    return "Type in either + - / * for operation";
  }
}

//Me testing it out
console.log(basicOp("+", 1, 2));

//Really smarter way of doing it is using eval
// function basicOp(o, a, b) {
//   return eval(a+o+b);
// }
