let arr = [{
    fieldName: 'hello',
    valueVOs: []
}, {
    fieldName: 'hello',
    valueVOs: []
}, {
    fieldName: '',
    valueVOs: []
}, {
    fieldName: 'hello',
    valueVOs: []
}, {
    fieldName: 'hello',
    valueVOs: []
}]
function trans (arr) {
    let index = arr.findIndex(a => a.fieldName === '') // 
    if (index !== -1) {
        return [arr.slice(0, index), arr.slice(index)]
    }
    return [arr.slice()]
}
trans(arr)



const getNewArray = (data) => {
    let newArray = [[],[]];
    data.forEach((val) => {
        if (val.fieldName === "") {
            newArray[1].push(val)
        } else {
            newArray[0].push(val)
        }
    })

    return newArray
}
getNewArray(data)
