Hack vs Smalltalk: What are the differences?

What is Hack? A programming language for HHVM that interoperates seamlessly with PHP. Hack provides instantaneous type checking via a local server that watches the filesystem. It typically runs in less than 200 milliseconds, making it easy to integrate into your development workflow without introducing a noticeable delay.

What is Smalltalk? An object-oriented, dynamically typed reflective programming language. It is an object-oriented, dynamically typed reflective programming language. It was created as the language underpinning the "new world" of computing exemplified by "human–computer symbiosis". It was designed and created in part for educational use, specifically for constructionist learning.

Hack and Smalltalk belong to "Languages" category of the tech stack.

        JavaScript
        JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
        Python
        Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
        Java
        Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
        HTML5
        HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

        Throughout 2016, Slack began migrating from PHP5 to Hack. They cite several well-known challenges inherent to PHP, including surprise type conversions, inconsistency around reference semantics, inconsistencies in the standard library, and the fact that “PHP tries very, very hard to keep the request running, even if it has done something deeply strange.”

        To overcome these challenges while maintaining the unique values of PHP, Slack turned to Hack, a gradual typing system for PHP. Hack runs on the HipHop Virtual Machine, or HHVM, an open source just-in-time (JIT) environment for PHP.
