splitEvery

(groupSize: number) => (sequence: Sequence) => Sequence[]

Split the sequence into groups of a size.

Try It

const splitEvery2 = splitEvery(2)

splitEvery2('abc') // is ['ab', 'c']
splitEvery2(['a', 'b', 'c']) // is [['a', 'b'], ['c']]

splitEvery2('') // is ['']
splitEvery2([]) // is [[]]
const splitEvery2 = splitEvery(2)

splitEvery2('abc') // is ['ab', 'c']
splitEvery2(['a', 'b', 'c']) // is [['a', 'b'], ['c']]

splitEvery2('') // is ['']
splitEvery2([]) // is [[]]

Try It

const splitEvery2 = splitEvery(2)

splitEvery2('abc') // is ['ab', 'c']
splitEvery2(['a', 'b', 'c']) // is [['a', 'b'], ['c']]

splitEvery2('') // is ['']
splitEvery2([]) // is [[]]
const splitEvery2 = splitEvery(2)

splitEvery2('abc') // is ['ab', 'c']
splitEvery2(['a', 'b', 'c']) // is [['a', 'b'], ['c']]

splitEvery2('') // is ['']
splitEvery2([]) // is [[]]

Sometimes we want to split a sequence into groups of a size. Below, we have a list of students. We're splitting them up into groups of 3 for a class project. Let's make the groups.

Try It

const students = ['mike', 'luke', 'emma', 'meg', 'tom']
const createGroupsOf3 = compose([shuffle, splitEvery(3)])

const groups = createGroupsOf3(students)
console.log(groups)
// is [
//   [group of 3]
//   [group of 2]
// ]
const students = ['mike', 'luke', 'emma', 'meg', 'tom']
const createGroupsOf3 = compose([shuffle<string>, splitEvery(3)<string[]>])

const groups = createGroupsOf3(students)
console.log(groups)
// is [
//   [group of 3]
//   [group of 2]
// ]

Try It

const students = [
  'mike',
  'luke',
  'emma',
  'meg',
  'tom',
]
const createGroupsOf3 = compose([
  shuffle,
  splitEvery(3),
])

const groups = createGroupsOf3(students)
console.log(groups)
// is [
//   [group of 3]
//   [group of 2]
// ]
const students = [
  'mike',
  'luke',
  'emma',
  'meg',
  'tom',
]
const createGroupsOf3 = compose([
  shuffle<string>,
  splitEvery(3)<string[]>,
])

const groups = createGroupsOf3(students)
console.log(groups)
// is [
//   [group of 3]
//   [group of 2]
// ]
