title: Introducing Else If Statements
challengeType: 1
videoUrl: 'https://scrimba.com/c/caeJ2hm'
forumTopicId: 18206
dashedName: introducing-else-if-statements
---
# --description--
If you have multiple conditions that need to be addressed, you can chain `if` statements together with `else if` statements.
```js
if (num > 15) {
return "Bigger than 15";
} else if (num < 5) {
return "Smaller than 5";
} else {
return "Between 5 and 15";
}
```
# --instructions--
Convert the logic to use `else if` statements.
# --hints--
You should have at least two `else` statements
```js
assert(code.match(/else/g).length > 1);
```
You should have at least two `if` statements
```js
assert(code.match(/if/g).length > 1);
```
You should have closing and opening curly braces for each `if else` code block.
```js
assert(
code.match(
/if\s*\((.+)\)\s*\{[\s\S]+\}\s*else\s+if\s*\((.+)\)\s*\{[\s\S]+\}\s*else\s*\{[\s\S]+\s*\}/
)
);
```
`testElseIf(0)` should return the string `Smaller than 5`
```js
assert(testElseIf(0) === 'Smaller than 5');
```
`testElseIf(5)` should return the string `Between 5 and 10`
```js
assert(testElseIf(5) === 'Between 5 and 10');
```
`testElseIf(7)` should return the string `Between 5 and 10`
```js
assert(testElseIf(7) === 'Between 5 and 10');
```
`testElseIf(10)` should return the string `Between 5 and 10`
```js
assert(testElseIf(10) === 'Between 5 and 10');
```
`testElseIf(12)` should return the string `Greater than 10`
```js
assert(testElseIf(12) === 'Greater than 10');
```
# --seed--
## --seed-contents--
```js
function testElseIf(val) {
if (val > 10) {
return "Greater than 10";
}
if (val < 5) {
return "Smaller than 5";
}
return "Between 5 and 10";
}
testElseIf(7);
```
# --solutions--
```js
function testElseIf(val) {
if(val > 10) {
return "Greater than 10";
} else if(val < 5) {
return "Smaller than 5";
} else {
return "Between 5 and 10";
}
}
```
