56533eb9ac21ba0edf2244dc	Chaining If Else Statements	1		链接如果其他声明

Description

if/else语句可以链接在一起以用于复杂的逻辑。这是多个链式if / else if语句的伪代码 ：

if（ condition1 ）{
语句1
} else if（ condition2 ）{
语句2
} else if（ condition3 ）{
声明3
。 。 。
} else {
statementN
}

Instructions

写入链接if / else if语句以满足以下条件： num < 5 - return“Tiny”
num < 10 - 返回“Small”
num < 15 - 返回“中”
num < 20 - 返回“Large”
num >= 20 - 返回“巨大”

Tests

tests:
  - text: 你应该至少有四个<code>else</code>语句
    testString: 'assert(code.match(/else/g).length > 3, "You should have at least four <code>else</code> statements");'
  - text: 你应该至少有四个<code>if</code>语句
    testString: 'assert(code.match(/if/g).length > 3, "You should have at least four <code>if</code> statements");'
  - text: 你应该至少有一个<code>return</code>语句
    testString: 'assert(code.match(/return/g).length >= 1, "You should have at least one <code>return</code> statement");'
  - text: <code>testSize(0)</code>应该返回“Tiny”
    testString: 'assert(testSize(0) === "Tiny", "<code>testSize(0)</code> should return "Tiny"");'
  - text: <code>testSize(4)</code>应该返回“Tiny”
    testString: 'assert(testSize(4) === "Tiny", "<code>testSize(4)</code> should return "Tiny"");'
  - text: <code>testSize(5)</code>应返回“Small”
    testString: 'assert(testSize(5) === "Small", "<code>testSize(5)</code> should return "Small"");'
  - text: <code>testSize(8)</code>应该返回“Small”
    testString: 'assert(testSize(8) === "Small", "<code>testSize(8)</code> should return "Small"");'
  - text: <code>testSize(10)</code>应该返回“Medium”
    testString: 'assert(testSize(10) === "Medium", "<code>testSize(10)</code> should return "Medium"");'
  - text: <code>testSize(14)</code>应返回“Medium”
    testString: 'assert(testSize(14) === "Medium", "<code>testSize(14)</code> should return "Medium"");'
  - text: <code>testSize(15)</code>应该返回“Large”
    testString: 'assert(testSize(15) === "Large", "<code>testSize(15)</code> should return "Large"");'
  - text: <code>testSize(17)</code>应该返回“Large”
    testString: 'assert(testSize(17) === "Large", "<code>testSize(17)</code> should return "Large"");'
  - text: <code>testSize(20)</code>应该返回“巨大”
    testString: 'assert(testSize(20) === "Huge", "<code>testSize(20)</code> should return "Huge"");'
  - text: <code>testSize(25)</code>应该返回“巨大”
    testString: 'assert(testSize(25) === "Huge", "<code>testSize(25)</code> should return "Huge"");'
