- `length` (*given a list, return the total number of items within it*);
- `map` (*given a function and a list, return the list of the results of applying `function(item)` on all items*);
- `foldl` (*given a function, a list, and initial accumulator, fold (reduce) each item into the accumulator from the left using `function(accumulator, item)`*);
- `foldr` (*given a function, a list, and an initial accumulator, fold (reduce) each item into the accumulator from the right using `function(item, accumulator)`*);

- `foldl` (*given a function, a list, and initial accumulator, fold (reduce) each item into the accumulator from the left*);
- `foldr` (*given a function, a list, and an initial accumulator, fold (reduce) each item into the accumulator from the right*);
- `reverse` (*given a list, return a list with all the original items, but in reversed order*).
