Removing Item from array with Underscore.js

Question

I have an array like this :

var array = [1,20,50,60,78,90];
var id = 50;

How can i remove the id from the array and return a new array tha

Answer 1

For the complex solutions you can use method _.reject(), so that you can put a custom logic into callback:

var removeValue = function(array, id) {
    return _.reject(array, function(item) {
        return item === id; // or some complex logic
    });
};
var array = [1, 20, 50, 60, 78, 90];
var id = 50;
console.log(removeValue(array, id));

For the simple cases use more convenient method _.without():

var array = [1, 20, 50, 60, 78, 90];
var id = 50;
console.log(_.without(array, id));
