Hey Team,

Just wanted to give you a heads up that I've added a cool resource to the web-developer-roadmap-2023. Now, under "Useful references" section there is one new helpful resource link which is handpicked to make life easier for folks learning about web development. I think that'll be super useful for everyone using the guide. Let me know what you think!

Cheers, Soham Mukherjee
