生成随机范围的数字，字符串等

export  default (quantity,minChar = 5,maxChar = 10,fn) => {
  let randomArray = [];
  while (randomArray.length < quantity){
    let num = Math.ceil(Math.random()*minChar*(maxChar/minChar));
    if (num >= minChar) randomArray.push(fn(num));
  }
  return randomArray;
}

usage

let items = random(30,25,30, num => random(num, 1, 22, index => 'qwertyuiopasdfghjklzxcvbnm'.substr(index, 1))
  .join(''))
  .map(value => content:value);
