 | 
					
						
							|  |  |  | `if/else` statements can be chained together for complex logic. Here is <dfn>pseudocode</dfn> of multiple chained `if` / `else if` statements: |

 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Write chained `if`/`else if` statements to fulfill the following conditions: | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `num < 5` - return "Tiny"   | 
					
						
							|  |  |  | `num < 10` - return "Small"   | 
					
						
							|  |  |  | `num < 15` - return "Medium"   | 
					
						
							|  |  |  | `num < 20` - return "Large"   | 
					
						
							|  |  |  | `num >= 20` - return "Huge" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | # --hints--
 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | You should have at least four `else` statements | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(code.match(/else/g).length > 3); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | You should have at least four `if` statements | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(code.match(/if/g).length > 3); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | You should have at least one `return` statement | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(code.match(/return/g).length >= 1); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(0)` should return "Tiny" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(testSize(0) === 'Tiny'); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(4)` should return "Tiny" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(testSize(4) === 'Tiny'); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(5)` should return "Small" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(testSize(5) === 'Small'); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(8)` should return "Small" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(testSize(8) === 'Small'); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(10)` should return "Medium" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(testSize(10) === 'Medium'); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(14)` should return "Medium" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(testSize(14) === 'Medium'); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(15)` should return "Large" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(testSize(15) === 'Large'); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(17)` should return "Large" | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ```js | 
					
						
							|  |  |  | assert(testSize(17) === 'Large'); | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | `testSize(20)` should return "Huge" | 
					
						
							|  |  |  | 
 |
