# --description--
|
||
|
|
||
|
The <dfn>less than</dfn> operator (`<`) compares the values of two numbers. If the number to the left is less than the number to the right, it returns `true`. Otherwise, it returns `false`. Like the equality operator, <dfn>less than</dfn> operator converts data types while comparing.
|
||
|
|
||
|
**Examples**
|
||
|
|
||
|
```js
|
||
|
2 < 5 // true
|
||
|
'3' < 7 // true
|
||
|
5 < 5 // false
|
||
|
3 < 2 // false
|
||
|
'8' < 4 // false
|
||
|
```
|
||
|
|
||
|
# --instructions--
|
||
|
|
||
|
Add the less than operator to the indicated lines so that the return statements make sense.
|
||
|
|
||
|
# --hints--
|
||
|
|
||
|
`testLessThan(0)` should return "Under 25"
|
||
|
|
||
|
```js
|
||
|
assert(testLessThan(0) === 'Under 25');
|
||
|
```
|
||
|
|
||
|
`testLessThan(24)` should return "Under 25"
|
||
|
|
||
|
```js
|
||
|
assert(testLessThan(24) === 'Under 25');
|
||
|
```
|
||
|
|
||
|
`testLessThan(25)` should return "Under 55"
|
||
|
|
||
|
```js
|
||
|
assert(testLessThan(25) === 'Under 55');
|
||
|
```
|
||
|
|
||
|
`testLessThan(54)` should return "Under 55"
|
||
|
|
||
|
```js
|
||
|
assert(testLessThan(54) === 'Under 55');
|
||
|
```
|
||
|
|
||
|
`testLessThan(55)` should return "55 or Over"
|
||
|
|
||
|
```js
|
||
|
assert(testLessThan(55) === '55 or Over');
|
||
|
```
|
||
|
|
||
|
`testLessThan(99)` should return "55 or Over"
|
||
|
|
||
|
```js
|
||
|
assert(testLessThan(99) === '55 or Over');
|
||
|
```
|
||
|
|
||
|
You should use the `<` operator at least twice
|
||
|
|
||
|
```js
|
||
|
assert(code.match(/val\s*<\s*('|")*\d+('|")*/g).length > 1);
|
||
|
```
