Eachless

• tiny package helps you avoid the nested loops (for-each hell)

# install
npm i -s eachless

// usage
var {Eachless} = require("eachless")

data = {
    "products":[{
        ...
        "orders":[{
            ...
            "tags":[{
                "label": "laptop",
                "id": "tag-1"
            }]
        }]
    },{
        ...
        "orders":[{
            ...
            "tags":[{
                "label": "smartphone",
                "id": "tag-2"
            },{
                "label": "keyboard",
                "id": "tag-3"
            }]
        }]
    }]
}

to iterate through all the tag labels, use

• example code:

const labelsIterator = Eachless(data,['products','orders','tags','label'])

for(const label of labelsIterator){
    console.log(label)
}

• result:

- laptop
- smartphone
- keyboard
