Benchmark: Immer vs Shallow copy vs Immutable Perf Test 3

HTML Preparation code:

<script src="https://unpkg.com/immer/dist/immer.umd.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/immutable/3.8.2/immutable.js"></script>

Script Preparation code:

//const { fromJS } = require('immutable');
var data = { items: {}, count: 0, keys: [] }

for (let index = 0; index < 100; index++) {
  data[index] = { id: index, name: `ITEM-${index}`, value: Math.random() }
  data.count++
  data.keys.push(index)
}

var NEW_ITEM_ID = data.count +1

var produce = immer.default

var im = Immutable.fromJS(data);

Tests:

immer
data = produce(data, draft => { draft.items[NEW_ITEM_ID] = { id: NEW_ITEM_ID, name: 'ITEM-NEW', value: 0 } draft.counter++ draft.keys.push(NEW_ITEM_ID) })
shallow copy
data = { ...data, items: { ...data.items, [NEW_ITEM_ID]: { id: NEW_ITEM_ID, name: 'ITEM-NEW', value: 0 } }, count: data.count +1, keys: [ ...data.keys, NEW_ITEM_ID] }
Immutable
var um = im.set('items', im.get('items').set(NEW_ITEM_ID, { id: NEW_ITEM_ID, name: 'ITEM-NEW', value: 0 })); um = um.set('count', um.count +1); um = um.set('keys', um.get('keys').push(NEW_ITEM_ID));
