A useful tool to manage array of object.
Sometimes it would be a headache to maintain and to manipulate an array of object. ListStore is just a Map wrapper Object that enhances the original Map object. It looks like a small "database" which will help you manage arrays in a rather comfortable way.
install
npm install xorderedlist
example
import OrderedList from 'xorderedlist'
const list = new OrderedList([{ id: 1, name: 'one' }])
console.log(list.size) // 1
list.push([{ id: 2, name: 'two' }])
list.unshift([{ id: 0, name: 'zero' }])
list.update([{ id: 1, name: 'update one'}])
list.insertOne({id: 1.5, name: 'one point five' }, 1)
list.delete([2])
list.findOne(0)
list.findList([1, 2])
list.mutate((orderedList) => {
return orderedList.values.map(v => {
v.name = 'mutate ' + v.name
})
