remove a array from collection based on condition in js lodash code example

Example 1: lodash remove multiple items from array

var colors = ["red","blue","green","yellow"];
var removedColors = _.remove(colors, function(c) {
    //remove if color is green or yellow
    return (c === "green" || c === "yellow"); 
});
//colors is now ["red","blue"]
//removedColors is now ["green","yellow"]

Example 2: lodash remove not in array

var a = [
  {id: 1, name: 'A'},
  {id: 2, name: 'B'},
  {id: 3,  name: 'C'},
  {id: 4, name: 'D'}
];
var removeItem = [1,2];
removeItem.forEach(function(id){
   var itemIndex = a.findIndex(i => i.id == id);
   a.splice(itemIndex,1);
});
console.log(a);
