Use the Conditional (Ternary) Operator

The conditional operator, also called the ternary operator, can be used as a one line if-else expression.

The syntax is:

condition ? statement-if-true : statement-if-false;

The following function uses an if-else statement to check a condition:

function findGreater(a, b) {

  if(a > b) {

    return "a is greater";

  }

  else {

    return "b is greater";

  }

}

This can be re-written using the conditional operator:

function findGreater(a, b) {

  return a > b ? "a is greater" : "b is greater";

}

Use the conditional operator in the checkEqual function to check if two numbers are equal or not. The function should return either true or false.
