Hey @V1shvesh, sorry for not responding sooner -- I didn't see your ping until just now.

Yes, anyone including you and @aashish-ak are welcome to work on this. If you are both going to work on it, you may want to coordinate on it so that your work doesn't overlap.

Thank you both for taking a look at this!

Hey @ckerr, I would like to help on this one!
I took a look in the docs and saw multiple API Reference sections where the example code can be "es6ified". I'm not sure if I should make a pull-request to each section, or group some of them together in the same PR. What do you recommend?
