Haskell的Javascript中缀操作符 [英] Haskell's infix operator for Javascript

问题描述

Javascript中是否有等价的构造？如果没有，你将如何创建一个？

下面是对中缀操作符在Haskell中做什么的简单解释：

什么是：infix操作符在Haskell中做什么？

解决方案

JavaScript没有列表类型，但它有 Array

您可以使用...

  var newArr = [val] .concat（arr）; 
  

或者，您可以使用 unshift（）前置到一个数组，但它会改变原始数据。

JavaScript没有：运算符，运算符重载或者看起来像运算符的方法，所以你不能得到和Haskell类似的语法。

Is there an equivalent construct in Javascript. If not, how would you create one?

Here's a straightforward explanation of what the infix operator does in Haskell:

What does the : infix operator do in Haskell?

解决方案

JavaScript doesn't have a list type, but it has Arrays.

You can use...

var newArr = [val].concat(arr);

Alternatively, you could use unshift() to prepend to an array, but it mutates the original.

JavaScript doesn't have a : operator, operator overloading or methods that look like operators, so you can't get a similar syntax as Haskell.
