获取数组中最长的那一项, 并且打印其位置和长度

var arr=[‘2sfw7ry2gfsgrqew7ruwer2‘,‘342‘,‘fasfe3‘,‘f45wr‘,‘fwds‘,‘yufg‘,‘53gfdgfsd3gd‘,‘f23sffd‘,‘fds‘,‘543dgdsyg‘]

var fn = function(arr) {
  let maxIndex = 0
  let long = 0
  let value = ‘‘
  for(let i =0;i<arr.length;i++) {
    let temp = arr[i].length
    if(temp >= long) {
      long = temp
      maxIndex = i
      value = arr[i]
    }  
  }
  console.log(‘最长的是:‘+value+"长度是:"+long+‘位置是:‘+maxIndex)
}
fn(arr)
