const MIN = 1000
const MAX = 9999

const myNumbers = [ 2355, 7235, 8135, 1762, 2361, 8351 ]

/* -------------------------------------------------------------------------- */

/**
 * Returns a random number, including the maximum and minimum.
 * @param {number} min
 * @param {number} max
 * @returns {number}
 */

const randomInRange = ( min, max ) => {
  const randomNumber = Math.floor( Math.random() * ( max - min + 1 ) + min )
  return randomNumber
}

/* -------------------------------------------------------------------------- */

/**
 *
 * @param {number} min
 * @param {number} max
 * @param {number[]} arr
 * @returns {number[]}
 */
const addRandomNumberToArray = ( min, max, arr ) => {
  /**
   * @type {number}
   */
  let randomNumber
  const updatedArray = [ ...arr ]
  // const updatedArray = arr.concat( [] )

  do {
    randomNumber = randomInRange( min, max )
  } while ( arr.includes( randomNumber ) )

  updatedArray.push( randomNumber )

  return updatedArray
}

const updatedArray = addRandomNumberToArray( MIN, MAX, myNumbers )

console.log( 'ORIGINAL ARRAY', myNumbers )
console.log( 'UPDATED ARRAY', updatedArray )
