if/else statements can be chained together for complex logic. Here is pseudocode of multiple chained if / else if statements:
```js
if (condition1) {
  statement1
} else if (condition2) {
  statement2
} else if (condition3) {
  statement3
. . .
} else {
  statementN
}
```
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"
else statements
    testString: assert(code.match(/else/g).length > 3);
  - text: You should have at least four if statements
    testString: assert(code.match(/if/g).length > 3);
  - text: You should have at least one return statement
    testString: assert(code.match(/return/g).length >= 1);
  - text: testSize(0) should return "Tiny"
    testString: assert(testSize(0) === "Tiny");
  - text: testSize(4) should return "Tiny"
    testString: assert(testSize(4) === "Tiny");
  - text: testSize(5) should return "Small"
    testString: assert(testSize(5) === "Small");
  - text: testSize(8) should return "Small"
    testString: assert(testSize(8) === "Small");
  - text: testSize(10) should return "Medium"
    testString: assert(testSize(10) === "Medium");
  - text: testSize(14) should return "Medium"
    testString: assert(testSize(14) === "Medium");
  - text: testSize(15) should return "Large"
    testString: assert(testSize(15) === "Large");
  - text: testSize(17) should return "Large"
    testString: assert(testSize(17) === "Large");
  - text: testSize(20) should return "Huge"
    testString: assert(testSize(20) === "Huge");
  - text: testSize(25) should return "Huge"
    testString: assert(testSize(25) === "Huge");
```
