| # --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');
 | |
| ```
 | |
|

 | |
| 
 | |
| ```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";
 | |
|   }
 | |
| }
 | |
| ```
