Answers use saved listing facts and recorded sources.

What it does

The Modern JavaScript Tutorial separates core language teaching from browser documents, events and interfaces.

Work through the language section before relying on browser-specific examples. That separation helps distinguish JavaScript concepts from the page environment around them. The contents move from variables and functions toward more advanced material, while a second part covers browser work. The tutorial map is useful when you need to return to one concept during a project. The language section starts from scratch and reaches object-oriented concepts. The online tutorial and its paid EPUB/PDF option are different access formats.
