other UI libraries Companies like Netflix make use of Angular JS on their consumer facing website, but for line of business apps you need a stable structure and rich set of components that is able to cope with displaying large datasets in an efficient manner, without impairing performance. For example: Ext JS includes a grid that buffers its rendering of data to the DOM. This means that out of a dataset of 100,000 records, about 30 – 40 rows may be rendered to the grid at a time, to optimize performance. As the user scrolls down, new rows are dynamically added, and old ones removed. Bootstrap UI is just HTML, so all data will be rendered to the DOM. This means that out of a dataset of 100,000 records, the entire dataset gets rendered to the page. This can severely impact performance, especially when there are other heavy components on the page. +
