You can also chain them together to check for multiple conditions. The following function uses `if`, `else if`, and `else` statements to check multiple conditions: ```js function findGreaterOrEqual(a, b) { if (a === b) { return "a and b are equal"; } else if (a > b) { return "a is greater"; } else { return "b is greater"; } } ``` The above function can be re-written using multiple conditional operators: ```js function findGreaterOrEqual(a, b) { return (a === b) ? "a and b are equal" : (a > b) ? "a is greater" : "b is greater"; } ``` It is considered best practice to format multiple conditional operators such that each condition is on a separate line, as shown above. Using multiple conditional operators without proper indentation may make your code hard to read. For example: ```js function findGreaterOrEqual(a, b) { return (a === b) ? "a and b are equal" : (a > b) ? "a is greater" : "b is greater"; } ``` # --instructions-- In the `checkSign` function, use multiple conditional operators - following the recommended format used in `findGreaterOrEqual` - to check if a number is positive, negative or zero. The function should return `positive`, `negative` or `zero`. # --hints-- `checkSign` should use multiple conditional operators ```js assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?\s*?\?\s*?.+?\s*?:\s*?.+?/gi.test(code)); ``` `checkSign(10)` should return the string `positive`. Note that capitalization matters ```js assert(checkSign(10) === 'positive'); ``` `checkSign(-12)` should return the string `negative`. Note that capitalization matters ```js assert(checkSign(-12) === 'negative'); ``` `checkSign(0)` should return the string `zero`. Note that capitalization matters ```js assert(checkSign(0) === 'zero'); ``` # --seed-- ## --seed-contents-- ```js function checkSign(num) { } checkSign(10); ``` # --solutions-- ```js function checkSign(num) { return (num > 0) ? 'positive' : (num < 0) ? 'negative' : 'zero'; } ```
