Falsy Bouncer|FreeCodeCamp

应该是没有get到题目的意思……

别人的代码

function bouncer(arr) {  // Don't show a false ID to this bouncer.  return arr.filter(isTrue);}function isTrue(ele){  if( ele ){    return ele;  }  }bouncer([7, "ate", "", false, 9])

function isjia(b) {var x = Boolean(b)return x;}function bouncer(arr) {// Don’t show a false ID to this bouncer.var filtered = arr.filter(isjia);return filtered;}bouncer([7, “ate”, “”, false, 9]);

自己写的

function bouncer(arr) {  // 请把你的代码写在这里  for(var i=0;i<arr.length;i++){    arr.filter(arr[i]=false||arr[i]=null||arr[i]=0||arr[i]=undifined||arr[i]=NaN||arr[i]="");  return arr;  }  }bouncer([7, "ate", "", false, 9]);
