这两条数据应该怎么处理?

data1和data2怎么处理成data3?我需要去data1中拿到data2的中文

let data3 = [];
data1.children.forEach(item1 => {
    if (!item1.children || !item1.children.length) return;
    item1.children.forEach(item2 => {
        let children = data2.filter(item3 => {
            return item3.siteId == item2.id
        }).map(item4 => {
            return {
               label: item4.i18n.default,
               value: item4.id, 
            }
        })
        data3.push({
            label: item2.i18n.default,
            value: item2.id,
            children: children,
        })
        
    })
})
