fort v0.1.0
fort
Sort, min, and max by a transform function.
example
minimum of some rows
var fort = require('fort');
var rows = [ { x : 5 }, { x : 3 }, { x : 2 }, { x : 9 } ];
var r = fort.min(rows, function (row) { return row.x });
console.dir(r);
{ x: 2 }
ascending rows
var fort = require('fort');
var rows = [ { x : 5 }, { x : 3 }, { x : 2 }, { x : 9 } ];
var res = fort.ascend(rows, function (row) { return row.x });
console.dir(res);
[ { x: 2 }, { x: 3 }, { x: 5 }, { x: 9 } ]
ascending modulo sort
var fort = require('fort');
var xs = [ 3, 2, 4, 6, 2, 8, 1, 7 ];
var res = fort.rise(xs, function (x) { return x % 4 });
console.dir(res);
[ 4, 8, 1, 2, 6, 2, 3, 7 ]
methods
fort.min(xs, f)
Return the minimum value from the elements in xs
after transforming by f(x)
on each element x
in xs
.
The return value will be from the original elements in xs
, not the transformed
set.
fort.max(xs, f)
Return the minimum value from the elements in xs
after transforming by f(x)
on each element x
in xs
.
The return value will be from the original elements in xs
, not the transformed
set.
fort.ascend(xs, f)
Return the elements from xs
sorted into ascending order after transforming by
f(x)
on each x
element in xs
.
The return array will be comprised of the original elements from xs
, not the
transformed values from f(x)
.
If xs
is a function or undefined, return a comparison function using
xs
or the identity as the function transform.
fort.descend(xs, f)
Return the elements from xs
sorted into descending order after transforming by
f(x)
on each x
element in xs
.
The return array will be comprised of the original elements from xs
, not the
transformed values from f(x)
.
If xs
is a function or undefined, return a comparison function using
xs
or the identity as the function transform.
fort.rise(xs, f)
Alias for fort.ascend()
that is more consistent with the fort theme of this
module.
fort.fall(xs, f)
Alias for fort.descend()
that is more consistent with the fort theme of this
module.
