Each object has a private property that contains a connection to its prototype, which is another object. That prototype object has its own prototype, and so on until you reach an object with null as its prototype. Null, by definition, has no prototype and serves as the last link in this chain of prototypes.
Currying is defined as when a function, rather of accepting all arguments at once, takes the first one and returns a new function, which then takes the second one and produces a new function, and so on until all arguments have been finished.
A closure is a function that has been packaged together (enclosed) with references to its surroundings (the lexical environment). In other words, a closure allows an inner function to access the scope of an outside function.
