To use

const { uniq } = require('./rdash')
const result = uniq([1,1,2,2,3,4,5])
console.log(result)

Output:
1,2,3,4,5

contains([arr], item)

const { contains } = require('./rdash')
const result = contains([1,2,3,4,5], 3)
console.log(result)

Output:
true

cumSum([arr])

const { cumSum } = require('./rdash')
const result = cumSum([1,2,3,4,5])
console.log(result)

Output:
Array [ 1, 3, 6, 10, 15 ]

groupBySumAt([arr], byKey, sumAt)

const { groupBySumAt } = require('./rdash')
var items = [
  {key:'key1', value:10},
  {key:'key2', value:20},
  {key:'key3', value:30},
  {key:'key1', value:40}
]
const result = groupBySumAt(items,'key','value')
console.log(result)

Output:
[{"key":"key1","value":50},{"key":"key2","value":20},{"key":"key3","value":30}]

console.log(result)

Output:
1,2,5,7,8,10

uniq([arr])

const { uniq } = require('./rdash')
const result = uniq([1,1,2,2,3,4,5])
console.log(result)

Output:
1,2,3,4,5

duplicates

const { duplicates } = require('./rdash')
const result = duplicates([1,8,2,1,7,5,2])
console.log(result)

Output:
[1,2,1,2]

factorial

const { factorial } = require('./rdash')
const result = factorial(3)
console.log(result)

Output:
6

isPrime

const { isPrime } = require('./rdash')
const result = isPrime(3)
