Methods

(generator, static) map(items, f)

Return a one-use generator that yields f(item) for each item of items. One-use: the returned generator object is a one use or temporary object.

Parameters:
Name Type Description
items Iterable

items to use
f function

mapping function
Yields:
`f(item)` for each `item` of `items`

(static) partial(f, …args) → {function}

Return a partial function that behaves like f called with the provided args. If any arguments are supplied in a call to the partial function, then they will immediately follow args in the call to f. If you let g denote a partial function of f, then a call to g(...supplied) will return f(...args, ...supplied).

Parameters:
Name Type Attributes Description
f function

function to partially apply
args * <repeatable>

arguments to provide for partial application
Returns:

(...supplied) => f(...args, ...supplied)

Type

The following two line are equivalent:

const log = gaius.partial(console.log, '[gaius]');
const log = (...supplied) => console.log('[gaius]', ...supplied);
