587d7b7e367417b2b2512b24	Use the Conditional (Ternary) Operator	1	301181

--description--

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

The syntax is:

condition ? expression-if-true : expression-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";
}

--instructions--

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

--hints--

checkEqual should use the conditional operator

assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?/.test(code));

checkEqual(1, 2) should return "Not Equal"

assert(checkEqual(1, 2) === 'Not Equal');

checkEqual(1, 1) should return "Equal"

assert(checkEqual(1, 1) === 'Equal');

checkEqual(1, -1) should return "Not Equal"

assert(checkEqual(1, -1) === 'Not Equal');

--seed--

--seed-contents--

function checkEqual(a, b) {

}

checkEqual(1, 2);

--solutions--

function checkEqual(a, b) {
  return a === b ? "Equal" : "Not Equal";
}
