# --description--
|
||
|
|
||
|
The <dfn>logical or</dfn> operator (`||`) returns `true` if either of the <dfn>operands</dfn> is `true`. Otherwise, it returns `false`.
|
||
|
|
||
|
The <dfn>logical or</dfn> 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"`.
|
||
|
|
||
|
# --hints--
|
||
|
|
||
|
You should use the `||` operator once
|
||
|
|
||
|
```js
|
||
|
assert(code.match(/\|\|/g).length === 1);
|
||
|
```
|
||
|
|
||
|
You should only have one `if` statement
|
||
|
|
||
|
```js
|
||
|
assert(code.match(/if/g).length === 1);
|
||
|
```
|
||
|
|
||
|
`testLogicalOr(0)` should return "Outside"
|
||
|
|
||
|
```js
|
||
|
assert(testLogicalOr(0) === 'Outside');
|
||
|
```
|
||
|
|
||
|
`testLogicalOr(9)` should return "Outside"
|
||
|
|
||
|
```js
|
||
|
assert(testLogicalOr(9) === 'Outside');
|
||
|
```
|
||
|
|
||
|
`testLogicalOr(10)` should return "Inside"
|
||
|
|
||
|
```js
|
||
|
assert(testLogicalOr(10) === 'Inside');
|
||
|
```
|
||
|
|
||
|
`testLogicalOr(15)` should return "Inside"
|
||
|
|
||
|
```js
|
||
|
assert(testLogicalOr(15) === 'Inside');
|
||
|
```
|
||
|
|
||
|
`testLogicalOr(19)` should return "Inside"
|
||
|
|
||
|
```js
|
||
|
assert(testLogicalOr(19) === 'Inside');
|
||
|
```
|
||
|
|
||
|
`testLogicalOr(20)` should return "Inside"
|
||
|
|
||
|
```js
|
||
|
assert(testLogicalOr(20) === 'Inside');
|
||
|
```
|
||
|
|
||
|
`testLogicalOr(21)` should return "Outside"
|
||
|
|
||
|
```js
|
||
|
assert(testLogicalOr(21) === 'Outside');
|
||
|
```
|
||
|
|
||
|
`testLogicalOr(25)` should return "Outside"
|
||
|
|
||
|
```js
|
||
|
assert(testLogicalOr(25) === 'Outside');
|
||
|
```
