What does this JQuery selector do in my Debut theme code?

Technical Q&A
1

Hey Guys,

I am new to JQuery and I am trying to understand how JQuery selectors work in particular. I am using the Debut theme for my website.

In theme.js under the function _createLineItemList I see something like the code below (line #8 in code dump below)

$(selectors.cartItemTitle, $item)

.text(item.product_title)

.attr(‘href’, item.url);

which I believe targets the below HTML

What does this JQuery selector do in the context of the function. It does not seem to be initialising a variable nor setting the data-attribute.

Below is a dump of the function for some reference

createLineItemList: function(state) {
      return $.map(
        state.items,
        function(item, index) {
          var $item = this.$itemTemplate.clone();
          var $itemPriceList = this.$itemPriceListTemplate.clone();

          this._setLineItemAttributes($item, item, index);
          this._setLineItemImage($item, item.featured_image);

          $(selectors.cartItemTitle, $item)
            .text(item.product_title)
            .attr('href', item.url);

          var productDetailsList = this._createProductDetailsList(
            item.product_has_only_default_variant,
            item.options_with_values,
            item.properties
          );
          this._setProductDetailsList($item, productDetailsList);
          this._setItemRemove($item, item.title);

          $itemPriceList.html(
            this._createItemPrice(
              item.original_price,
              item.final_price,
              this.$itemPriceListTemplate
            )
          );

          if (item.unit_price_measurement) {
            $itemPriceList.append(
              this._createUnitPrice(
                item.unit_price,
                item.unit_price_measurement,
                this.$itemPriceListTemplate
              )
            );
          }

          this._setItemPrice($item, $itemPriceList);

          var itemDiscountList = this._createItemDiscountList(item);
          this._setItemDiscountList($item, itemDiscountList);

          this._setQuantityInputs($item, item, index);

          var itemLinePrice = this._createItemPrice(
            item.original_line_price,
            item.final_line_price,
            this.$itemLinePriceTemplate
          );
          this._setItemLinePrice($item, itemLinePrice);

          return $item[0];
        }.bind(this)

Can someone please throw some light on this.
