arraySample: An TS/JS array util when you want an evenly distributed sample of values from an array

arraySample.util.ts

const arraySample = (array: any[], targetSampleLength: number): any[] => {
  const currentLength = array.length
  if (currentLength <= targetSampleLength) {
    return array
  }
  const lastIndex = array.length - 1
  const increment = Math.ceil(currentLength / targetSampleLength)

  let newArray = []

  while (newArray.length <= targetSampleLength) {
    const i: number = newArray.length === 0 ?
      0 : newArray.length * increment

    if (
      newArray.length === targetSampleLength - 1
    ){
      newArray.push(array[lastIndex])
      break
    } else {
      newArray.push(array[i])
    }

  }
  return newArray
}
