All

Operating system

All

Steps to reproduce this

I found a handful of typos, omissions, and errors in the reference while reviewing it this week 🤦🏽‍♂️ Here's a quick rundown:

• stroke() -- ...after calling stroke() will be outlined with the color orange...
• fill() -- The version of fill() with four parameters... is missing
• background() -- The version of background() with four parameters... is missing
• endShape() -- Stops adding vertices to a custom shape.
• shearY() -- In the example comments, // Shear the coordinate system along the **y**-axis.
• applyMatrix() -- Broken link: https://en.wikipedia.org/wiki/Transformation_matrix
• arc() -- The sentence "Arcs are always drawn clockwise from start to stop." is repeated; the second copy should be deleted.

Hi @perminder-17,

I would like to work on this issue. Could you please assign it to me?

Thanks!

[perminder-17]

Sure, thanks for taking this.

[Nitin2332]

can you clarify in which branch i should open the PR @perminder-17

[perminder-17]

As said above

p5.js version
= 1.9(ish)

So it would be on the main branch but if issue persist in 2.x version you can open up a PR on dev-2.0 branch as well. Thanks

@perminder-17 oops, I actually typed >= 1.9(ish) into the issue template and didn't realize it would be formatted as markdown. It looks like most/all errors are still present in 2.x -- found the same error in the stroke() reference.

Thanks for the help @Nitin2332! I feel silly for missing these.
