--- id: 56533eb9ac21ba0edf2244d9 title: Comparisons with the Logical Or Operator challengeType: 1 videoUrl: 'https://scrimba.com/c/cEPrGTN' forumTopicId: 16800 --- ## Description
The logical or operator (||) returns true if either of the operands is true. Otherwise, it returns false. The logical or operator is composed of two pipe symbols: (||). This can typically be found between your Backspace and Enter keys. The pattern below should look familiar from prior waypoints: ```js if (num > 10) { return "No"; } if (num < 5) { return "No"; } return "Yes"; ``` will return "Yes" only if num is between 5 and 10 (5 and 10 included). The same logic can be written as: ```js if (num > 10 || num < 5) { return "No"; } return "Yes"; ```
## Instructions
Combine the two if statements into one statement which returns "Outside" if val is not between 10 and 20, inclusive. Otherwise, return "Inside".
## Tests
```yml tests: - text: You should use the || operator once testString: assert(code.match(/\|\|/g).length === 1); - text: You should only have one if statement testString: assert(code.match(/if/g).length === 1); - text: testLogicalOr(0) should return "Outside" testString: assert(testLogicalOr(0) === "Outside"); - text: testLogicalOr(9) should return "Outside" testString: assert(testLogicalOr(9) === "Outside"); - text: testLogicalOr(10) should return "Inside" testString: assert(testLogicalOr(10) === "Inside"); - text: testLogicalOr(15) should return "Inside" testString: assert(testLogicalOr(15) === "Inside"); - text: testLogicalOr(19) should return "Inside" testString: assert(testLogicalOr(19) === "Inside"); - text: testLogicalOr(20) should return "Inside" testString: assert(testLogicalOr(20) === "Inside"); - text: testLogicalOr(21) should return "Outside" testString: assert(testLogicalOr(21) === "Outside"); - text: testLogicalOr(25) should return "Outside" testString: assert(testLogicalOr(25) === "Outside"); ```
## Challenge Seed
```js function testLogicalOr(val) { // Only change code below this line if (val) { return "Outside"; } if (val) { return "Outside"; } // Only change code above this line return "Inside"; } // Change this value to test testLogicalOr(15); ```
## Solution
```js function testLogicalOr(val) { if (val < 10 || val > 20) { return "Outside"; } return "Inside"; } ```
