如何永久启用Sublime Text 3 LiveReload插件(How to permanently enable Sublime Text 3 LiveReload plugin)

 用括号括起来，就像这样 
 
getInitialState: () => ({
    text: this.props.text
})
 
 如果没有括号，对象文字看起来也像一个带有名为text的标签的JavaScript块。 由于它不明确，因此抛出SyntaxError。 但当你用()包围它时，JavaScript知道它是一个Object文字。 
 
 
 
 
 我认为现在这个箭头功能受到限制 
 
 
 箭头功能没有this 。 当在箭头函数中遇到this情况时，它将转到上一级以查看this是否在那里可用并使用它。 你可以像这样确认一下 
 
(function Test1() {
  console.log(this);
  (() => console.log(this))();
}).bind({a: 1})();
 
 会打印 
 
{ a: 1 }
{ a: 1 }
 
 在您的情况下， this将引用声明它的函数的this对象，而不是对象本身。 

Surround it with parenthesis, like this
 
getInitialState: () => ({
    text: this.props.text
})
 
without the parenthesis, the object literal looks also like a JavaScript block with a label called text in it. Since it is ambiguous, the SyntaxError is thrown. But when you surround it with (), JavaScript knows that it is an Object literal.
 
 
 
 
I think this is being bound now to that arrow function
 
 
Arrow functions don't have this. When this is encountered in an arrow function, it will go to previous level to see if this is available there and use that. You can confirm that, like this
 
(function Test1() {
  console.log(this);
  (() => console.log(this))();
}).bind({a: 1})();
 
would print
 
{ a: 1 }
{ a: 1 }
 
In your case, this will refer the this object of the function in which it is declared, not the object itself.
