If you are new to front-end web development and have no clue where to start, I can recommend the Front-end Handbook written by Cody Lindley. The book briefly discusses all the topics relevant for front-end development, what’s important and what not and links to a large set of resources to help you grasp and understand each of these topics in more detail.
It is the perfect learning path to help you getting started with front-end web development.
