Should all be fixed now! See https://github.com/James-Livesey/atto/pull/7 for more details. In the end, using `input` still wasn't sufficient to fix the lag, so instead I 'bodged' the delay before rendering happens by adding a 10 ms wait between keydown and render. But yes, you were right in thinking that `hidInput` wasn't 'ready' for the renderer to get the value of!

Hi there! I'm the creator of this programming language. I've designed this language to resemble the style of the BASIC programming languages of the 80s, but with the modern functionality of today (syntax highlighting, rich editing, fast runtime, runs in browser etc.). It's a bit of a side project of mine, but ultimately I think it's a great way for beginners to learn programming, and for more advanced users to tinker with! You can get help by using the `help` command, and we have many tutorials to get you started with, in addition to a command reference. Whilst our documentation is still work-in-progress, your feedback is most welcome — let me know what you think is good about the documentation, but also what you think could be improved, too. atto is open source, so feel free to check out (and maybe star‽) the GitHub repo: https://github.

Looks like their own basic interpreter. There's a list of keywords here: https://github.com/James-Livesey/atto/blob/main/commands.js#... There are some drawing commands, getpixel, etc.
