Why can't I use lodash's remove() function?

Question

I'm using Laravel 5.5. I've run npm install and npm run dev and generally I have a good working environment with running Javascript, but I've been caught out while trying to use lodash's remove() function to remove an element from an array.

var array = [1, 2, 3, 4];
var evens = _.remove(array, function(n) {
    return n % 2 == 0;
});

The above code produces the following error:

TypeError: _.remove is not a function

Lodash is loaded in resources/assets/js/bootstrap.js.

window._ = require('lodash');

Other lodash methods works fine.

_.each([1, 2], function(n) {
    console.log(n);
});

Any idea why I can't use .remove()?

The problem was that I'm also using Laravel Spark. Spark does not use resources/assets/js/bootstrap.js and loads its own bootstrap at vendor/laravel/spark/resources/assets/js/spark-bootstrap.js instead.

Spark's bootstrap actually requires the underscore package instead of lodash, hence the confusion.

window._ = require('underscore');
