How can i eliminate the duplicate inside the assets?
See the image, i need to eliminate the list with ID duplicate, where is the cross. I try with this map and filter, but the problem i lost the rest of the attribute, as a results i need to have the same structure but with out the duplicate id inside the assets[]
let known = new Set();
let listArrayDoc = this.documentsfiltered.map(subarray => subarray['assets'].filter(item => !known.has(item.id) && known.add(item.id)));

In the map you have to return the entire object updating only the assets prop, you can achieve that returning {...subarray, assets: filteredArray} in the map function

Solution:
