Basic Mathematical Operations.js

/*
Description:
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:

basicOp('+', 4, 7)         // Output: 11
basicOp('-', 15, 18)       // Output: -3
basicOp('*', 5, 5)         // Output: 25
basicOp('/', 49, 7)        // Output: 7
*/

function basicOp(o, a, b) {
  return eval(a+o+b);
}
