--- id: 587d7b7e367417b2b2512b24 title: Use the Conditional (Ternary) Operator challengeType: 1 --- ## Description
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";
}
## Instructions
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.
## Tests
```yml tests: - text: checkEqual should use the conditional operator testString: assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?/gi.test(code), 'checkEqual should use the conditional operator'); - text: checkEqual(1, 2) should return false testString: assert(checkEqual(1, 2) === false, 'checkEqual(1, 2) should return false'); - text: checkEqual(1, 1) should return true testString: assert(checkEqual(1, 1) === true, 'checkEqual(1, 1) should return true'); - text: checkEqual(1, -1) should return false testString: assert(checkEqual(1, -1) === false, 'checkEqual(1, -1) should return false'); ```
## Challenge Seed
```js function checkEqual(a, b) { } checkEqual(1, 2); ```
## Solution
```js function checkEqual(a, b) { return a === b ? true : false; } ```
