The Curious Case of Blazing Fast Front-End JS Frameworks

Create A Website for $1.99/Month

Javascript frameworks need no introduction. As pervasive as JS is on the Internet—being one of the core technologies that make up the web, along with CSS and HTML—it comes with a host of problems if coding best practices aren’t followed. That’s where frameworks come in. 

Not only do frameworks provide an easy solution to common programming problems, they make coding easy for large teams due to their propensity towards standardisation. While each framework comes with its own set of unique problems to solve for, they make life easy for developers by saving resources in the long run.

However, there is an interesting trend in newer front-end frameworks; their claim of being ‘blazing fast’. JS code is notorious for adding loading time to websites, reducing time-to-interaction for users, increasing bounce rate, and causing an overall erosion in user experience. These new frameworks are not only optimised from the ground up for speed, but also come with a host of unique solutions to get past the anachronisms of using JS to make feature-filled, easy-to-use, and maintenance-free websites. 

In this article, we’ll take a look at some novel solutions implemented in modern front-end JS frameworks to improve loading times, user experience, and make web development easier for all. 

Qwik offers lazy-loading solution

Qwik is a framework built on top of JSX by the creator of ‘Angular’, Misko Hevery. It solves the problem of slow loading times by being a fully lazy-loadable system. Lazy loading is an approach to loading elements that delays the initialisation of resources until they are actually required to be displayed. This saves a lot of resources on the client and server side and vastly improves the loading time. 

Moreover, Qwik also has a built-in optimizer that takes an application and breaks it up into a lot of small, lazy-loading chunks. It also incorporates a library called ‘Partytown’, which delegates third-party…
