Javascript is a structurally typed language, meaning two objects are compatible as long as they share the same structure (i.e., the same set of properties and methods). Learn javascript's 7 primitive types: string, number, bigint, boolean, undefined, null, and symbol. understand immutability, typeof quirks, and autoboxing. learn how javascript primitives and objects differ in behavior. A lot of concepts are confusing and overwhelming for developers but a good knowledge of these concepts will help you in the long run. frameworks and libraries come and go but the fundamentals always remain the same. In javascript, closures are created every time a function is created, at function creation time. to use a closure, define a function inside another function and expose it. one powerful use of closures is to use the outer function as a factory for creating functions that are somehow related.
