Methods
(static) by(relation, compare) → {function}
A utility for creating a comparator function for a particular aspect of a
figurative class of objects.
Parameters:
Name | Type | Description |
---|---|---|
relation |
function | A function that accepts a value and returns a corresponding value to use as a representative when sorting that object. |
compare |
function | an alternate comparator for comparing the represented values. The default is `Object.compare`, which does a deep, type-sensitive, polymorphic comparison. |
- Source:
Returns:
a comparator that has been annotated with
`by` and `compare` properties so
`Array#sorted` can perform a transform that reduces the need to
call `by` on each sorted object to just once.
- Type
- function
(static) identity(any) → {Any}
A utility to reduce unnecessary allocations of `function (x) {return x}` in
its many colorful but ultimately wasteful parameter name variations.
Parameters:
Name | Type | Description |
---|---|---|
any |
Any | value |
- Source:
Returns:
that value
- Type
- Any
(static) noop()
A utility to reduce unnecessary allocations of `function () {}`
in its many colorful variations. It does nothing and thus makes a suitable
default in some circumstances.
