Advanced Javascript Basics for Web Developers
summary
Starts by demonstrating value versus reference semantics with numbers versus arrays and shows hoisting by declaring a local var after use so the function logs undefined rather than the global value; explains closures and hoisting explained with concrete console outputs. Shows currying/partial application to build small adders, then dismantles callback pyramids using call/apply to rebind context and Array.prototype.slice to turn arguments into arrays. Covers Constructors, prototypes and inheritance, recommending Object.create for safe inheritance and showing how new binds this.
