I recommend if you can use Javascript libraries such as underscore or lodash, look at .uniq function. .uniq - Underscore.js - _.uniq - Lodash

So when you have the final array(menuProduitSet):

// by menu.menuId:
var byMenuId = _.uniq(menuProduitSet, function(m){ return m.menu.menuId; }); 

// by produit.prodId 
var byProdId = _.uniq(menuProduitSet, function(m){ return m.produit.prodId; });
