Inferno vs Preact: What are the differences?

Developers describe Inferno as "A fast, React-like JavaScript library for building UIs". Inferno is an isomorphic library for building high-performance user interfaces, which is crucial when targeting mobile devices. Unlike typical virtual DOM libraries like React, Mithril, Virtual-dom, Snabbdom and Om, Inferno uses techniques to separate static and dynamic content. This allows Inferno to only "diff" renders that have dynamic values. On the other hand, Preact is detailed as "A fast 3k React alternative". Preact is an attempt to recreate the core value proposition of React (or similar libraries like Mithril) using as little code as possible, with first-class support for ES2015. Currently the library is around 3kb (minified & gzipped).

Inferno and Preact belong to "Javascript UI Libraries" category of the tech stack.

"Faster than React" is the primary reason why developers consider Inferno over the competitors, whereas "Lightweight" was stated as the key factor in picking Preact.

Inferno and Preact are both open source tools. It seems that Preact with 23.1K GitHub stars and 1.2K forks on GitHub has more adoption than Inferno with 13.8K GitHub stars and 636 GitHub forks.

Decisions about Inferno and Preact
Chose
Preact
over
React

Preact offers an API which is extremely similar to React's for less than 10% of its size (and createElement is renamed to h, which makes the overall bundle a lot smaller). Although it is less compatible with other libraries than the latter (and its ecosystem is nowhere as developed), this is generally not a problem as Preact exposes the preact/compat API, which can be used as an alias both for React and ReactDOM and allows for the use of libraries which would otherwise just be compatible with React.

What are some alternatives to Inferno and Preact?
React
Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
Svelte
If you've ever built a JavaScript application, the chances are you've encountered – or at least heard of – frameworks like React, Angular, Vue and Ractive. Like Svelte, these tools all share a goal of making it easy to build slick interactive user interfaces. Rather than interpreting your application code at run time, your app is converted into ideal JavaScript at build time. That means you don't pay the performance cost of the framework's abstractions, or incur a penalty when your app first loads.
jQuery
jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.
AngularJS
AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding.
jQuery UI
Whether you're building highly interactive web applications or you just need to add a date picker to a form control, jQuery UI is the perfect choice.
