Syntax

var T any,
  args ...any,
  accumulator any,
  reducer (any, T)=>any,
  init (...args=>accumulator)|accumulator

reduce.sync(reduce, init?)(...args) -> any

Synchronous reduce without promise handling. Only for arrays (for now)

const add = (a, b) => a + b

console.log(
  reduce.sync(add, 0)([1, 2, 3, 4, 5]),
) // 15

1. Implement

• head – returns the first element
• last – the opposite of head; returns the last element
• tail - all elements except the first one
• reduceRight – similar to how we implemented reduce
• concat – takes in n-arrays and combines them. So concat(arr1, arr2, ...arrN)
• take – returns the first n elements of an array. So take(n)(arr)
• takeWhile – `takeWhile(condition)(a
