On a side note, if someone asks me to prototype anything on Java world, will pick Grails. Getting a webpage up and running in Grails is so easy.

Which version of Grails was that? If you mean version 3, why is virtually no-one starting new projects in it, or upgraded from v.2 ? Grails 3 looks like nothing more than a wrapper around Spring Boot, so why not just use that? If you're talking about version 2, why has its plugin ecosystem died?

Same issue on mobile Chrome.

Cool. I was seeing source of inner js, which in deed uses proxies to create structural sharing.

I love this idea. I always, take a famous open source project and try to re-create or go through the source of it. Its very tough, but when you do so the learning is very immense. Thanks for the link.

Late comment but a good way to do this when you're digging through the source and look at the early commits to see where it started. I remember going through Linux 0.0.1 to boil down the essentials of the kernel for example.

With react context in place now starting from 16.3, I guess we can start using them for app level storage rather going to tools like redux.

It looks very similar to Either functor (left which always return nothing). Looks cool though.

Yup saw that few days ago. But I wanted to build this for a long time.

I always wanted to ask this. I'm a full stack developer with good knowledge on Java and JavaScript. I'm currently reading Golang especially for its concurrency idioms. It is good and easy to write concurrent code but people always come and say about actors which are very good when compared with channels. I have never used actors before.. Whats your thoughts on this?

Well not sure, if this helps. But I wrote a simple tutorial on locks and RWMutex. The project builds a simple in memory database, may be helpful to you: https://github.com/antoaravinth/go_concurrency_tutorial

In Chennai, India where I live many government school doesn't have a computer. For these students computer is a dream. I remember how students from these schools visited our office and touched a computer for their first time. Its really sad to see this at my hometown.
