如何使用Ramda对单词数组进行排序?

import R from 'ramda'

const names = ['Khan', 'Thanos', 'Hulk']

const sortNamesAsc = R.sortBy(R.identity) // alphabetically
const sortNamesDesc = R.pipe(sortNamesAsc, R.reverse)

sortNamesAsc(names) // ['Hulk', 'Khan', 'Thanos']
sortNamesDesc(names) // ['Thanos', 'Khan', 'Hulk']

Ramda Repl example

别想这么做 字符串-使用 localeCompare

const trees = ["cedar", "elm", "willow", "beech"]
console.log("Sorted trees", R.sort((a, b) => a.localeCompare(b), trees))

您可以使用 R.comparator 和 R.lt :

const trees = ["cedar", "elm", "willow", "beech"]
const result = R.sort(R.comparator(R.lt), trees)
console.log("Sorted trees", result)

这就是你所说的用拉姆达排列单词的意思吗?

import R from 'ramda'
var objs = [ 
    { first_name: 'x', last_name: 'a'     },
    { first_name: 'y',    last_name: 'b'   },
    { first_name: 'z', last_name: 'c' }
];
var ascendingSortedObjs = R.sortBy(R.prop('last_nom'), objs)
var descendingSortedObjs = R.reverse(ascendingSortedObjs)
