--- id: 587d7b7e367417b2b2512b24 title: Use the Conditional (Ternary) Operator challengeType: 1 forumTopicId: 301181 dashedName: use-the-conditional-ternary-operator --- # --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". # --hints-- `checkEqual` should use the `conditional operator` ```js assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?/.test(code)); ``` `checkEqual(1, 2)` should return "Not Equal" ```js assert(checkEqual(1, 2) === 'Not Equal'); ``` `checkEqual(1, 1)` should return "Equal" ```js assert(checkEqual(1, 1) === 'Equal'); ``` `checkEqual(1, -1)` should return "Not Equal" ```js assert(checkEqual(1, -1) === 'Not Equal'); ``` # --seed-- ## --seed-contents-- ```js function checkEqual(a, b) { } checkEqual(1, 2); ``` # --solutions-- ```js function checkEqual(a, b) { return a === b ? "Equal" : "Not Equal"; } ```
