Hello all,

I'm working since many days in the file odoo-8.0-20151203/openerp/addons/point_of_sale/static/src/js/models.js

For example, in this file, we can find these two lines :

            var all_taxes = _(this.compute_all(product_taxes, base)).flatten();
                        _(all_taxes).each(function(tax) {
                         [...]

What is the utility of the _ (underscore) in those lines?

Thank for your help.
