Python Hard Theory

Iterable vs iterator, custom iterators, generators, and `send`/`throw`/`close`

An iterable can produce an iterator, an iterator yields values one at a time, generators are a compact way to build iterators, and advanced generator methods can push values or exceptions back in.

Iterables and iterators are not the same
Generators implement the iterator protocol for you
`send`, `throw`, and `close` control generator execution

JavaScript Medium Theory

Iteration in JavaScript: for, while, do while, for...of, for...in, iterables, iterators, generators, and yield

JavaScript supports several loop forms, plus iterator and generator protocols for custom iteration behavior.

`for...of` iterates values
`for...in` iterates enumerable property keys
Generators pause and resume with `yield`
