如何重构我的条件声明？

Question

我试图用这个条件语句缩短我的代码

我有

  if(title =='project'){
      title = text + ': ' + this.projectTitle;
  }else{
      title = this.projectTitle;
  }

我觉得有更好的方法可以重写这个。有谁知道怎么做？

谢谢！

Answer 1

尝试ternary：

title = (title =='project') ? text + ': ' + this.projectTitle: this.projectTitle;

Answer 2

复制if / else：

的三元组

title = title == 'project' ? text + ': ' + this.projectTitle : this.projectTitle;

虽然你真的想缩短它：

title = (title == 'project' ? text + ': ' : '') + this.projectTitle;
