Description
if/else
утверждения могут быть объединены вместе для сложной логики. Вот псевдокод операторов с несколькими цепями if
/ else if
: если ( условие 1 ) {
statement1
} else if ( условие2 ) {
оператор2
} else if ( условие 3 ) {
оператор3
, , ,
} else {
statementN
}
Instructions
if
/ else if
выражения для выполнения следующих условий: num < 5
- return "Tiny" num < 10
- возврат "Small" num < 15
- возврат "Средний" num < 20
- возврат "Большой" num >= 20
- возврат "Огромный"
Tests
tests:
- text: You should have at least four <code>else</code> statements
testString: assert(code.match(/else/g).length > 3);
- text: You should have at least four <code>if</code> statements
testString: assert(code.match(/if/g).length > 3);
- text: You should have at least one <code>return</code> statement
testString: assert(code.match(/return/g).length >= 1);
- text: <code>testSize(0)</code> should return "Tiny"
testString: assert(testSize(0) === "Tiny");
- text: <code>testSize(4)</code> should return "Tiny"
testString: assert(testSize(4) === "Tiny");
- text: <code>testSize(5)</code> should return "Small"
testString: assert(testSize(5) === "Small");
- text: <code>testSize(8)</code> should return "Small"
testString: assert(testSize(8) === "Small");
- text: <code>testSize(10)</code> should return "Medium"
testString: assert(testSize(10) === "Medium");
- text: <code>testSize(14)</code> should return "Medium"
testString: assert(testSize(14) === "Medium");
- text: <code>testSize(15)</code> should return "Large"
testString: assert(testSize(15) === "Large");
- text: <code>testSize(17)</code> should return "Large"
testString: assert(testSize(17) === "Large");
- text: <code>testSize(20)</code> should return "Huge"
testString: assert(testSize(20) === "Huge");
- text: <code>testSize(25)</code> should return "Huge"
testString: assert(testSize(25) === "Huge");
Challenge Seed
function testSize(num) {
// Only change code below this line
return "Change Me";
// Only change code above this line
}
// Change this value to test
testSize(7);
Solution
function testSize(num) {
if (num < 5) {
return "Tiny";
} else if (num < 10) {
return "Small";
} else if (num < 15) {
return "Medium";
} else if (num < 20) {
return "Large";
} else {
return "Huge";
}
