How to Use Lodash in Vue Component Template?

In a Vue component, you can use Lodash by importing specific methods or the entire library into your script section. Lodash methods can be applied in computed properties or methods for efficient data manipulation, helping to keep your Vue templates clean and optimized.

Prerequisites

• Javascript
• VueJs
• loadash

Approach

• The products array contains product objects with name and price properties, defined in the data() section of the Vue component.
• In Vue 2, a global cheapProducts filter is applied directly in the template using v-for="(product, index) in products | cheapProducts", which filters out expensive products.
• The filtered list of products is rendered in the ul element, displaying only products with prices less than 50.
• Each product in the v-for loop is assigned a unique key (index) to ensure Vue optimally tracks the changes.
