|  | localeTitle: 调用函数时捕获以错误顺序传递的参数 | |||
|  | --- | |||

 | |||
|  | ## Description
 | |||
|  | <section id="description">继续讨论调用函数,需要注意的下一个错误是函数的参数是以错误的顺序提供的。如果参数是不同的类型,例如期望数组和整数的函数,则可能会引发运行时错误。如果参数是相同的类型(例如,所有整数),那么代码的逻辑将没有意义。确保以正确的顺序提供所有必需的参数以避免这些问题。 </section> | |||
|  | 
 | |||
|  | ## Instructions
 | |||
|  | <section id="instructions">函数<code>raiseToPower</code>将基数提升为指数。不幸的是,它没有被正确调用 - 修复代码,因此<code>power</code>值是预期的8。 </section> | |||
|  | 
 | |||
|  | ## Tests
 | |||
|  | <section id='tests'> | |||
|  | 
 | |||
|  | ```yml | |||
|  | tests: | |||
|  |   - text: 你的代码应该固定可变<code>power</code>因此它等于2提升到3功率,而不是3增加到2功率。 | |||
|  |     testString: 'assert(power == 8, "Your code should fix the variable <code>power</code> so it equals 2 raised to the 3rd power, not 3 raised to the 2nd power.");' | |||
|  |   - text: 您的代码应使用<code>raiseToPower</code>函数调用的正确参数顺序。 | |||
|  |     testString: 'assert(code.match(/raiseToPower\(\s*?base\s*?,\s*?exp\s*?\);/g), "Your code should use the correct order of the arguments for the <code>raiseToPower</code> function call.");' | |||
|  |
