inside template           {{#items}} loop I do this:

<div class="grid--full display-table">
                                      <div class="grid__item">
                                         {{{retNextDiscount itemQty properties }}}
                                      </div>
                                  </div>
                                  
                                  
helper in Custom Javascript is this:

Handlebars.registerHelper('retNextDiscount', function (qty, properties) {
  if(typeof properties.subscription_id === 'string') {
    return '';
  }
  qty = Number(Handlebars.escapeExpression(qty));
  if(qty === 1) {
     return '<small class="ucdcart-item__discount">5% off when buying 2</small><br>';
  } else if (qty === 2) {
     return '<small class="ucdcart-item__discount">10% off when buying 3 or more</small><br>';
  } else if (qty >= 3) {
     return '<small class="ucdcart-item__discount">You\'re getting our best discount! (10%)</small><br>';
  }  
});

I want to add SKU argument to function, so I can process discount text with SKU of variant
