basically what the title says - for debugging purpose I want to get the version as a constant variable. I checked each variable in “this” but didn’t get anything relevant matches /version/i

```auto
function setup() {
  createCanvas(400, 400);
  console.log(Object.keys(this).filter(s=>s.match(/version/i)))
}

function draw() {
  background(220);
}

```

By looking at [https://editor.p5js.org/app.f1745ed387a63eb59417.js](https://editor.p5js.org/app.f1745ed387a63eb59417.js) (the js file used by [editor.p5js.org](http://editor.p5js.org)) it seems like 1.1.9 is only shown in two URLs, nowhere in the code.

And it’s in the first line of [https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.1.9/p5.js](https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.1.9/p5.js)

> I’m also puzzled why devs from both Processing Java & p5js flavors so adamantly refuse to add some way for a sketch to inspect which version it is running on. crazy_face Indeed the p5 constructor doesn’t contain any info about its version. The only place I’ve found it was inside the “p5.js” file itself on its 1st line as a comment block. Take a look at these 2 examples below. 1st is from the current “v1.1.9” and 2nd is from a very old “v.0.2.3”: /\*! p5.js v1.1.9 July 22, 2020 \*/: [cdn.…](http://cdn.JsDelivr.net/npm/p5@1.1.9)

Congrats @micuat I see you have got it implemented in p5 1.3.1 as VERSION. Working well for me. That’s taken a long time, the p5 team didn’t see it as important.
