--- id: 587d7b7e367417b2b2512b24 title: Use the Conditional (Ternary) Operator challengeType: 1 forumTopicId: 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: ```js 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: ```js 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".
## Tests
```yml tests: - text: checkEqual should use the conditional operator testString: assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?/.test(code)); - text: checkEqual(1, 2) should return "Not Equal" testString: assert(checkEqual(1, 2) === "Not Equal"); - text: checkEqual(1, 1) should return "Equal" testString: assert(checkEqual(1, 1) === "Equal"); - text: checkEqual(1, -1) should return "Not Equal" testString: assert(checkEqual(1, -1) === "Not Equal"); ```
## Challenge Seed
```js function checkEqual(a, b) { } checkEqual(1, 2); ```
## Solution
```js function checkEqual(a, b) { return a === b ? "Equal" : "Not Equal"; } ```
