Why?

Why migrate from EZ-Script to JavaScript? The answer is performance and functionality. While EZ-Script appears straightforward, it is very similar to JavaScript. The most significant differences will be outlined in this tutorial. However, JavaScript can organize commands in groups, called classes. These command groups make JavaScript more organized and easier to find the correct command that you're looking for.

Performance


The Synthiam implementation of JavaScript in ARC is fast... very fast! It outperforms EZ-Script by a significant magnitude. Take for instance, a benchmark between the two languages by counting to 1,000,000.

Wow that is totally great info to know, thanks!

Thanks for this Tutorial @DJ. It will be invaluable as I change over my many scripts from EZ Script to JavaScript! I'm excited to see how my robot's arm servo react to the new faster language. I have some pretty complex scripts (for me anyway. LOL).

I think you'll find that the new scripts you write will be even smaller and faster. Probably easier to read as well. I can always help you change some over if you post one. That'll give you examples of how the difference would be.

But just to be clear, the EZ scripts should still mostly work in Arc? I tried 2 that still worked no conversion. Just slower most likely.

Yeah, EZ-Script works in ARC. This is a tutorial to help people migrate to a faster and more feature-rich language.

Oh boy, it seems everyone is getting covid these days. I'm feeling left out. I hope you're doing well and binge-watching a lot of tv! Drink soup and dream about robots.

Thanks DJ. I'm coming to the end of it I hope. Feeling better. Don't feel left out. Only good thing about this is now I have some antibodies for a while. LOL. Stay healthy!

Actually i was adding some script codes for my Init servos start up and other start up functions, then realized I used EZ script instead of Javascript. Since Javascript is way faster ,what is the easy way to convert the EZ script over to Javascript? right now it just wants to delete the whole EZ script when I move into Javascript window. Like if I copy and paste it in, will it convert? I guess I can just start over line by Line with the cheat helper
Edit.... I think I had a similar question last week about using my old EZ scripts and did you point out some tutorial Link? I seem to have forgot where.

*Note: I moved your question to the appropriate thread because it was asked on a feature request for Blockly copy and paste

The windows Copy and Paste command will copy the text. There is no way to "convert code" when pasting. It will merely paste what is copied. Once you paste the EZ-Script into the JavaScript window, you can edit the code to make it JavaScript syntax.

There used to be an option for that. Hmmm. I can't seem to find it now. I'll have to take a better look as I don't see it in the documentation on the support section.
