Solution in JavaScript (node.js v5.12) (judge verdict: Wrong Answer)

var A;
var B;

var result = (A,B) => {
  if ( A+B > A-B) {
		if (A+B > A*B) {
 			console.log(A+B);
  	  } else {
    	console.log(A*B);
      }
 }else {
  	    if (A-B > A*B) {
			console.log(A-B);
      } else {
			console.log(A*B);
      }
	}
 };

result(A,B);
