## Description
|
|||
|
|
<section id="description">使用以下方法填写对象构造函数： <blockquote> getFirstName（）getLastName（）getFullName（）setFirstName（first）setLastName（last）setFullName（firstAndLast） </blockquote>运行测试以查看每个方法的预期输出。采用参数的方法必须只接受一个参数，并且必须是一个字符串。这些方法必须是与对象交互的唯一可用方法。如果卡住，请记得使用<a href="http://forum.freecodecamp.org/t/how-to-get-help-when-you-are-stuck/19514" target="_blank">Read-Search-Ask</a> 。尝试配对程序。编写自己的代码。 </section>
