方案二

let data = [3, undefined, 6, null, 7, '', "", [9], [], { name: '舒冬' }, {}, 5, '半晨'],
    result = data.filter(item => !item == '' && !item == "" && ![undefined, 'undefined', null, 'null', [], '[]', {}, '{}'].includes(JSON.stringify(item)));
    
console.log(result);
// (7) [3, 6, 7, Array(1), {…}, 5, '半晨']
