Ramda Title Case

ramda-title-case.js

import R from 'ramda';

const capitalize =
  R.converge(
    R.concat,
    [
      R.compose(
        R.toUpper,
        R.head
      ),
      R.tail,
    ]
  );

const toTitleCase =
  R.compose(
    R.join(' '),
    R.map(capitalize),
    R.split(' ')
  );

Great! I'd suggest removing parentheses in R.concat() part, as they are not needed here, and it looks like function runs w/o arguments.

const R = require('ramda')

const capitalize =
  R.converge(
    R.concat(), [
      R.compose(
        R.toUpper,
        R.head
      ),
      R.tail,
    ]
  );

const titleCase =
  R.compose(
    R.join(' '),
    R.map(capitalize),
    R.split(' '),
    R.toLower,
  );

console.log('typeof titleCase:', typeof(titleCase))
console.log(titleCase('how do you like this?'))
console.log(titleCase('RAMDA FUNCTIONS RETURN FUNCTIONS.'))

// Results
// typeof titleCase: function
// How Do You Like This?
// Ramda Functions Return Functions.
