[英]How can I make this code more 'functional programming' style in Ramda.js / lodash
I have this bit of code: 我有这段代码:
var fn = function(fn, name) {
this.commands.add(name, fn);
}.bind(this);
_.mapObjIndexed(fn, this.commandList);
I feel like there's a way to improve this bit of code and make it just one line. 我觉得有一种方法可以改进这段代码,使其仅一行。 I tried many different ways, but I'm new to
ramda.js
and I might be missing some function, that would make this easier and simpler. 我尝试了许多不同的方法,但是我对
ramda.js
,我可能会缺少一些功能,这会使此操作变得更加容易和简单。
You seem to be looking for the flip
function / flip
function : 您似乎在寻找
flip
功能 / flip
功能 :
_.mapObjIndexed(_.flip(this.commands.add), this.commandList);
If a .bind(this.commands)
for the add
function is necessary, you can shorten that using _.bindKey (this.commands, "add")
. 如果需要
add
函数的.bind(this.commands)
,则可以使用_.bindKey (this.commands, "add")
来缩短它。
If the flipping doesn't work correctly because of the number of arguments, you might needt to throw in _.ary(…, 2)
or _.binary(…)
. 如果由于参数数量而导致翻转无法正常进行,则可能不需要输入
_.ary(…, 2)
或_.binary(…)
。
