WordPress – the most popular CMS on the web, is great for allowing users with non technical skills to update and modify websites. WP combined with AngularJS allows developers to create some crafty apps for their clients. Since Angular works with custom HTML directives and JSON, data can be added for various interactions. One popular use is to showcase a product with a lot of details – for example computer with different specs. A website user can interact with a gallery, viewing different products while having the various data loaded. Angular is made by Google, so most web developers will have this JavaScript Framework in their toolset.
