[英]What means the “->” in node.js
I'm trying to learn about the connect-livereload module and after installing it, is written this : 我正在尝试了解connect-livereload模块,并在安装后将其编写为:
Next, import: 接下来,导入:
app.configure 'development', ->
app.use require('connect-livereload') 35729
is that " -> " sign just a typo or what it stands for ? 是“ -> ”符号只是错字还是代表错字? i would suppose it's just a typo if these two lines weren't chained with just a comma so that's why i ask.
我想如果这两条线不是只用逗号链接,那只是一个错字,所以这就是我问的原因。
->
is an operator used in CoffeScript
. ->
是CoffeScript
使用的运算符。
Functions are defined by an optional list of parameters in parentheses, an arrow, and the function body.
函数由括号中的可选参数列表,箭头和函数体定义。
That's not JavaScript, it's CoffeeScript . 那不是JavaScript,而是CoffeeScript 。 It's a function.
这是一个功能。 The JavaScript translation is:
JavaScript的翻译是:
app.configure('development', function() {
return app.use(require('connect-livereload'), 36729);
});
that is nothing node specific. 这与节点无关。 That code is writting in coffeescript
该代码写在coffeescript中
in javascript that is the same as 在javascript中与
app.configure('development', function() {
return app.use(require('connect-livereload')(35729));
});
