lodash remove from array code example

Example 1: lodash remove element from list

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

Example 2: Lodash remove duplicates from array

var users = [
  {id:1,name:'ted'},
  {id:1,name:'ted'},
  {id:1,name:'bob'},
  {id:3,name:'sara'}
];
var uniqueUsersByID = _.uniqBy(users,'id'); //removed if had duplicate id
var uniqueUsers = _.uniqWith(users, _.isEqual);//removed complete duplicates

Example 3: 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 4: remove element from array lodash

var arr = [1, 2, 3, 3, 4, 5];
_.remove(arr, function(e) {
    return e === 3;
});
console.log(arr);

Example 5: 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);
