-const sum = numbers.reduce((acc, n) =>acc + n, 0);

 Just like for .map and .filter methods, .reduce is applied on an array and takes a function as the first parameter.

 ### Generators
 
-Another way to write the `downToOne` function is to use a Generator. To instantiate a `Generator` object, one must use the `function *` declaration. Generators are functions that can be exited and later re-entered with its context (variable bindings) saved across re-entrances.

 Generators return an iterable object. When the iterator's `next()` function is called, it is executed until the first `yield` expression, which specifies the value to be returned from the iterator or with `yield*`, which delegates to another generator function. When a `return` expression is called in the generator, it will mark the generator as done and pass back as the return value. Further calls to `next()` will not return any new values.
