--description--

if/else语句串联在一起可以实现复杂的逻辑,这是多个if/else if语句串联在一起的伪代码:

if (condition1) {
  statement1
} else if (condition2) {
  statement2
} else if (condition3) {
  statement3
. . .
} else {
  statementN
}

--instructions--

if/else if语句串联起来实现下面的逻辑:

num < 5- return "Tiny"
num < 10- return "Small"
num < 15- return "Medium"
num < 20- return "Large"
num >= 20 - return "Huge"

--hints--

你应该有至少 4 个else表达式。

assert(code.match(/else/g).length > 3);

你应该有至少 4 个if表达式。

assert(code.match(/if/g).length > 3);

你应该有至少 1 个return表达式。

assert(code.match(/return/g).length >= 1);

testSize(0)应该返回 "Tiny"。

assert(testSize(0) === 'Tiny');

testSize(4)应该返回 "Tiny"。

assert(testSize(4) === 'Tiny');

testSize(5)应该返回 "Small"。

assert(testSize(5) === 'Small');

testSize(8)应该返回 "Small"。

assert(testSize(8) === 'Small');

testSize(10)应该返回 "Medium"。

assert(testSize(10) === 'Medium');

testSize(14)应该返回 "Medium"。

assert(testSize(14) === 'Medium');

testSize(15)应该返回 "Large"。

assert(testSize(15) === 'Large');

testSize(17)应该返回 "Large"。

assert(testSize(17) === 'Large');

testSize(20)应该返回 "Huge"。

assert(testSize(20) === 'Huge');

testSize(25)应该返回 "Huge"。

assert(testSize(25) === 'Huge');

--seed--

--seed-contents--

function testSize(num) {
  // Only change code below this line


  return "Change Me";
  // Only change code above this line
}

testSize(7);

--solutions--

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";
  }
}
