JavaScript to WebAssembly: Evolution or Revolution?

For the month of July, we are joining forces with our friends at JavaScriptMN meetup to discuss WebAssembly. I hope to see active participation and friendly knowledge share from all attendees as we discuss the future of web with WebAssembly, and what it means for JavaScript?

Please note: DATE and LOCATION has changed. We will be meeting on 22nd of July at CoCo location in uptown.


Google for the term "WebAssembly"! Lately, its all over the tech news world, and its about time we talk about it as a group and learn more.

Google, Microsoft, Mozilla, Apple and others are joining forces to bring WebAssembly to life! yes, they all seem to be in preliminary agreement that this would be a necessary evolution and a good thing to happen!!

Nobody knows for sure how quickly WebAssembly will take over the world, but if it does, how would it affect the SDLC of tomorrow? Even if WebAssembly standard/specification gains foothold, that does not mean browsers will stop supporting JavaScripts in near future, so very likely, we will see these two co-exist for at least a decade!

What will likely change is... skill set required for new application development projects will tilt more towards WebAssembly side within next 3 to 5 years.

• The next step in the evolution of JavaScript and asm.js is to do away with both of them. (arsTechnica) 

• JavaScript creator Eich's latest project: KILL JAVASCRIPT (theRegister)

It has been a long time dream of many to "dethrone" JavaScript programming language from browsers, and replace it with a compiled/bytecode-based solution. Three years ago, I too talked about the need and possibility of a somewhat of a thick-client sort of user experience rendering when I presented at MinneBar7 in 2012 (see slides 9, 10, 11 at

Goal of this session is to discuss and understand what it is, how skill set requirements will change for projects of tomorrow, and what would world look like if WebAssembly is widely adopted.

From Ketan's presentation at MinneBar7 in 2012 :


6:00pm to 6:30pm - Food and merriment (sponsored by the JavaScriptMN group), open networking, connect with others, make friends. Bring business cards.

6:30pm to 7:00pm  - Sponsor recognition, announcements and more

7:00pm to 8:30pm - Lets talk about WebAssembly!

Remember to not park in the CVS Lot! Plenty of parking in the surrounding area.

    This the video from the last meetup. Due to a bad cable the audio is a little off.

    I saw this article a few hours ago, I'm excited about this Meetup. Javascript is Dead, Long Live Javascript.

      lol First web design now JS? I'm starting to think this is a new headline trend for copywriters.

    Most of the articles I have been reading about WebAssembly have been saying that it isn't going to replace JavaScript. Even the guy who made JS is saying that it isn't going away:
    "No, JS isn’t going away in any foreseeable future. Yes, wasm should relieve JS from having to serve two masters. This is a win-win plan."

    Other blogs saying similar things:

    Personally I am glad because I am about to go to Prime and learn JS and I don't want my education to immediately be irrelevant. I hope the people working on WebAssembly really focus on making the View Source language really user friendly so we can keep the transparency and teach-yourself by looking at other people's examples and openness of the web.

      Martha, first of all, learning JavaScript in-depth is a good thing because there is A LOT OF DEMAND out there for that skill-set and I am almost certain that for next decade, there will be! You can't go wrong with it, so congratulations on your decision to pursue it. Your education is not likely to become irrelevant by any measure! As far as transparency etc., today we have minified or obfuscated JS already exists, and still there is lot of open source content and solution available! I do not see why someone could not open source their webassembly work, and almost certain that there will be a ton of open source projects and libraries that we will be able to borrow and learn from. Thanks for sharing links. Cheers!

    Martha, I don't think that Javascript is likely to be irrelevant in our lifetime. It's worth learning. It's worth learning in depth.

    Please note: this meetup has been rescheduled to July to allow us to discuss this topic while WebAssembly announcement is still fresh.
